For once the tag line has it just right: “You’ll never know how close we came.”

It may seem like a movie script, but it really happened. American planes took photos of Soviet missiles in Cuba, a “massively destabilizing move.” If they had been armed, they could have wiped out most of the mainland US population in five minutes. President John F. Kennedy had written a book while he was in college about the failure of England to respond to German aggression when it still might have been possible to prevent World War II. But he had also made his own mistake — a bad one — by responding too aggressively at the Bay of Pigs. Advisors like Dean Acheson and the military urged him to bomb the sites. But Adlai Stevenson says, “One of us in the room should be a coward,” and he asks the President to come up with a diplomatic solution. Kennedy knows better than to fight the last war, but he is not sure how to fight the next one.

There is no time spent on introductions or exposition, giving the story a sense of immediacy and urgency. It will leave audiences reminding themselves that we are still here, so it must have turned out all right. The President and his advisors argue about what to do (“Bombing them sure would feel good!”), interrupted by “just as usual” events to avoid letting the press or the Soviets suspect that anything was going on. When President Kennedy tells Chicago Mayor Daley that he “wouldn’t miss this event for the world,” we appreciate the literal meaning of his words.

Producer Kevin Costner plays a real person, Kennedy staffer Kenny O’Donnell, but the character combines the roles and actions of several people and essentially exists to help tell the story as efficiently as possible. Most of the time, he blends in with a large, capable cast of character actors (though he seems to make himself too important in a pep talk scene and at the end there is a sort of “Three Musketeers” shot that seems inappropriate).

Parents should know that the movie features brief strong language. Most of the movie is very tense, and a character is killed.

This is an outstanding movie, with much for families to talk about. Parents and grandparents should tell children any memories they may have of the Cuban missile crisis. They should talk about what we do when we have hard choices to make — President Kennedy and his brother, his closest advisor, listen to advice from experts, but, as the President says, “There is something immoral about abandoning your own judgment.” At the end of the day, he realizes that “there’s no wise old men; there’s just us.” Why does Kenny O’Donnell say that the only word in politics is “loyalty?” Why did the Soviets send a message through a reporter instead of using diplomatic channels? Why was it important for Adlai Stevenson to make a strong statement at the UN? Why did they ignore the second letter from Kruschev? How did that change things? What must someone do in order to direct soldiers to take actions that may get them killed? Who told the truth and who lied? Why?

Families who enjoy this movie will also enjoy “Air Force One” and some of the books and documentaries about President Kennedy and his brother, Robert Kennedy. DVD note: This first release from Infinifilm demonstrates shows us why the DVD technology was developed. It is packed with extras that are genuinely thrilling, from commentary by the real-life participants to a copy of the shooting script. Families with DVD players should consider this treasure for their permanent collection.

At the heart of a sex farce is someone who wants to have sex (preferably illicit) but is amusingly thwarted. This gives us the best of both worlds, as we get to vicariously enjoy the illicit possibilities and feel righteously smug about the agonies the characters go through in pursuit of their quest.

The problem these days is in finding believable excuses for keeping the characters apart. Not quite in the category of believable, even within the low credibility threshold of a comedy is this movie’s premise: Josh Hartnett plays Matt, a web designer who gives up sex for Lent.

To make him a more sympathetic character, we find out that his real problem is that he can’t get over Nicole, the girl who dumped him. Though he tries and tries to have consequenceless sex with a series of girls who could have the Sports Illustrated swimsuit models feeling insecure, it just doesn’t make him happy. So he decides to go completely without for 40 days and nights. At first, he feels liberated and in control. But every first-act set-up requires a second-act complication, and it arrives in the form of the lithe and lissome Erica (Shannyn Sossamon of “A Knight’s Tale”). He enjoys getting to know her without jumping into bed, but after a while it becomes awkward. And when she finds out what he is doing and that there is actually a website devoted to whether he will last for 40 days, she feels hurt and betrayed. And then Nicole re-enters the picture.

This is a very raunchy and explicit comedy but it is all done with sweetness and even a certain humility that keeps it from being too disgusting. Hartnett and Sossnanan are stronger on the romance than the comedy but they have a nice chemistry and we can’t help rooting for them. Erica’s friend is played by Maggie Gyllenhaal, who seems to have real potential, with an adorable smile and wickedly perfect delivery.

Parents should know that this movie has extremely explicit (often humiliating) sexual situations and references, including casual sex, masturbation, nudity, Viagra, pornography (one tape is titled: “In Diana Jones and the Temple of Poon”), a same-sex kiss, overall skanky behavior, and a used condom. A woman has sex with a man without his consent (he is tied to the bed and thinks she is someone else). There is very strong language. Characters drink and smoke. Some viewers will be offended by the portrayal of a Catholic seminarian (Matt’s brother), who is having his own problems with the vow of chastity.

Families who see this movie should talk about how Matt sees the world differently (literally and metaphorically) as a result of his vow. How would his relationship with Erica have been different if he had not taken the vow? Why was he unable to enjoy casual sex – was it really his lingering feelings for Nicole or was it a sense that he had not connected with her any more than he did with his one night stands?

Viewers who enjoy this movie will also enjoy “American Pie.”

Bobby Bowfinger (Steve Martin) wants desperately to make a movie, and as he approaches his 50th birthday he thinks he is running out of time. He tries to interest a studio executive in a script called “Chubby Rain,” written by an accountant, and is told the studio will make the movie IF Bowfinger can get Kit Ramsey, Hollywood’s biggest action star, to agree to appear in it. When Ramsey (Eddie Murphy) won’t even look at the script, Bowfinger decides to go ahead and make the movie around him, just filming him wherever he is without telling him anything about it.

Bowfinger takes his $2184 lifetime stash and gets started, with the help of a studio gofer who borrows the equipment (Jamie Kennedy), a very theatrical stage actress (Christine Baranski), and an ambitious ingenue literally just off the bus from Ohio (Heather Graham), who plans to become a star in one week. They set up the camera wherever Ramsey is going to be, and just stage the various scenes around him.

Ramsey, already high-strung and paranoid, finds his worst fears coming true as he is followed by strange people who say completely incomprehensible things to him about aliens and keep calling him “Keith.” He seeks help from Terry Stricter (Terrence Stamp), a counselor at Mind Head, a kooky therapy/religion whose members wear pyramid hats and recite affirmations. Meanwhile, Bowfinger needs a Ramsey look-alike for close- ups, and recruits the nerdy Jeff (also Eddie Murphy). And the ingenue sleeps with anyone and everyone who can help her get more time on screen.

The movie has some very funny moments but is oddly low-key, from its slow set-up of the premise to its lack of follow-through on some of the comic possibilities. Some of the humor may be too inside for those who do not follow Hollywood gossip. Watching Martin, Murphy, Baranski, and Graham — all in fine form here — is reason enough to see any movie, but in this case the script (written by Martin) is not as strong as it could have been.

Parents should know that the movie has a number of sexual references. The character played by Heather Graham has (offscreen) sex with just about every other character (male and female) purely to advance her career. While this is played for humor, without any suggestion that she is being exploited (quite the other way around), parents may want to talk to kids who see this movie about this behavior, as well as the choices Bowfinger himself makes by cheating, stealing, blackmailing, and lying to get his movie made. Some kids may have questions about “Mind Head”-style organizations. It might be fun to talk about what kind of movie could be made by filming family members as they go about their daily lives.

The classic fairy tale by Charles Perrault is lovingly and imaginatively brought to life in this animated Disney version, also a classic. Cinderella, a sweet, docile, and beautiful girl forced to act as a servant for her mean stepmother and stepsisters, goes to the ball with the help of her fairy godmother. But her godmother warns that the beautiful coach and gown will only last until midnight. Cinderella meets the Prince at the ball, and they share a romantic dance. But when the clock begins to strike midnight, she runs away, leaving behind one of her glass slippers. The Prince declares he will marry the girl whose foot fits that slipper. He finds her, and they live happily ever after.

Disney expanded the simple story with vivid and endearing characters and memorable songs. The animation is gorgeously detailed and inventive. In one musical number, as the stepsisters squawk their way through their singing lesson in another room, Cinderella sings sweetly as she scrubs the floor, reflected in dozens of soap bubbles.

When Cinderella asks if she can go to the ball, her stepmother tells her she can, if she can make an appropriate dress. She then keeps Cinderella much too busy to have time to make the dress. But Cinderella’s friends, the mice and birds, make one for her in another delightful musical number. As the fairy godmother sings “Bibbidi Bobbidi Boo,” she transforms a pumpkin into a coach, the mice into horses, the horse into a coachman, and finally, Cinderella’s rags into a magnificent ballgown. The scene when the Duke comes looking for the girl whose foot will fit the glass slipper is very suspenseful and highly satisfying.

While the story has enduring appeal, many people are troubled by the passive heroine, who meekly accepts her abusive situation and waits to be rescued, first by her godmother and then by the Prince. It is worth discussing, with both boys and girls, what some of her alternatives could have been (“If you were Cinderella, would you do what that mean lady told you?”), and making sure that they have some exposure to stories with heroines who save themselves. A superb book called Ella, Enchanted by Gail Carson Levine has an ingenious explanation for the heroine’s obedience.

In today’s world of blended families, it might also be worth discussing that not all step-parents and siblings are mean. Even children who are living with intact families of origin may need to hear this so that they will not worry about their friends.

Families who see this movie should talk about these questions: Why does Cinderella do what her stepmother says? What could she have done instead? Why is the King so worried about whether the Prince will get married? If you had a fairy godmother, what would you like her to do for you? Or would you like to be a fairy godmother? Whose wish would you grant?

This story has been told many times, and families might enjoy seeing sme of the other versions, including “Cinderfella,” with Jerry Lewis as the title character and Ed Wynn as his fairy godfather. The made-for- television musical version starring Leslie Ann Warren, with songs by Rogers and Hammerstein, and the remake with Brandi and Whitney Houston are available on video and well worth watching. Drew Barrymore’s revisionist “Ever After” gives us a spirited Cinderella who rescues herself.

Children might be amused to hear the rumor that Cinderella’s most famous accessory is the result of a mistake. It is often reported that in the original French story, her slipper was made of fur. But a mistranslation in the first English version described it as glass, and it has stayed that way ever since. But in reality, while there have been many versions of the story over the years, the best-known early written version, by Charles Perrault, did describe her slippers as glass. Other versions have her wearing gold slippers or a ring that fits only the true Cinderella.
