Chicken Run” has arrived to the joy and relief of the many fans of Nick Parks’ Oscar-winning Wallace and Gromit short films. In his studio’s first feature-length movie, a brave chicken plots an escape from a small Yorkshire chicken farm.

The stern and angry Mrs. Tweedy (voice of Miranda Richardson) and her brow-beaten (should we say hen-pecked?) husband have bullied their hens into producing eggs, but now they have set up a fierce-looking machine that turns chickens into chicken pies. Ginger (voice of Julia Sawalha) is a smart, brave, loyal chicken who will not leave unless she can take the others with her. When an American circus rooster named Rocky (voice of Mel Gibson) arrives, Ginger gets him to agree to teach the chickens to fly over the fence, so they can find a place where they can live in freedom.

Parks is a master at creating a world that is enchantingly believable. The farm seems to be set in the 1950’s, and every detail, down to the last nail in the last board on the hen house wall, looks exactly as it should. Though his painstaking process produces only a few seconds of film footage each day, every frame is filled with vivid personalities who seem to be moving in real time, each creating an instantly recognizable character. One look at Mrs. Tweedy’s formidable Wellington boots marching into the hen yard for inspection, and we know everything about her. The chickens are highly individual, completely believable, and wildly funny, whether doing Tae-Bo-like exercises for increasing wing power or a celebratory Lindy hop. But I admit that my favorite characters are two forager/thief rats who are so completely charming that it is impossible to imagine anyone objecting to their stealing.

The movie also features Parks’ special talents for creating deliciously malevolent machines and split-second action sequences. Ginger and Rocky fall into the chicken pie machine for a scene that combines Rube Goldberg complexity of gears and operations with the breath-catching near misses of Indiana Jones.

Three cheers for producer Dreamworks, who let Parks be Parks and didn’t focus-group him into making something more linear and accessible. What that means, though, is that the movie does not have some of what both adults and kids expect in a G-rated movie. This is not a musical in which the heroine sits down 15 minutes into the story to sing about her dreams or adorable sidekicks provide comic relief.

This is not a script with jokes that children will necessarily understand. Indeed, given that most of the parents of today’s school-age children were born 20 years after the 1950’s, there are several jokes parents may not understand, like a pointed reference to the delay in the US entry into World War II and a couple of witty tributes to the classic movie, “The Great Escape.” The movie has a decidedly British point of view, with a wonderful range of accents that will be much more meaningful (and understandable) to English children than they are to Americans. Parks is like Bugs Bunny creator Chuck Jones, who, when asked whether he made cartoons for adults or children, replied, “I make them for myself and my friends.” But, as with Bugs Bunny, kids will enjoy the world created by this movie, and will rejoice in the chickens’ adventures.

Parents should know that although the movie is rated G, it may be too scary or hard to follow for children under 6 or 7. A minor character is killed off-screen and characters are in peril throughout the movie.

Families who see this movie should talk about why it was hard for Rocky to tell the truth, and even to understand what telling the truth meant, as when he said, “I didn’t lie to them, dollface. I just omitted certain truths,” and when he tells Ginger that if they want the chickens to perform they have to tell them what they want to hear. Talk, too, about Ginger’s perseverance in the face of “million to one” odds, and her refusal to escape without her friends, and about the importance of leadership and teamwork. Ask kids why Ginger had a dream of freedom that some of the other chickens could not even imagine, and what it meant to say that “the fences aren’t just around the farm – they’re up here on your head.”

Families who enjoy this movie will also enjoy Parks’ Wallace and Gromit videos: “The Wrong Trousers,” “A Grand Day Out,” and “A Close Shave.

The better you remember the early 70’s, the more you will enjoy this very funny movie. It purports to reveal the “Deep Throat” who gave the Washington Post the inside information that led to President Nixon’s resignation. And come to think of it, in many ways this makes more sense than what we’ve been led to believe is the real story. According to this film, the downfall of the Nixon administration was caused by two 15-year- old girls who are so dim that H.R. Haldeman (Dave Foley) says, “I’ve met yams who have more going on upstairs than those two.”

Besty (Kirsten Dunst) and Arlene (Michelle Williams) are bubble-headed best friends who accidentally see a burgler breaking into the Watergate when they sneak out to mail in an entry to the “Why I should win a date with Bobby Sherman” contest at Tiger Beat magazine. The next day, they spot the same man (Harry Sherer as Gordon Liddy) while they are on a White House tour. Worried that they might tell someone, President Richard Nixon (Dan Hedaya) tries to co-opt them by appointing them “official White House dog walkers” and “secret teen advisors.”

At first the girls are thrilled, and they believe the President when he tells them that the massive shredding of documents they stumbled upon is for his hobby of paper mache. Arlene even develops a crush on “Dick” and is swooningly recording an Olivia Newton John song for him when she accidentally erases 18 1/2 minutes from one of his tapes. When she hears on the tape that he is not what he seemed, the two girls decide to talk to the Washington Post reporters and end up turning over the key evidence in a parking garage.

Boomer parents who lived through the 1970’s will enjoy this visit to the worst hair and clothes decade of the century. It is a clever tweak on the “Forrest Gump” concept, as the two girls turn out to be responsible for many of the best-remembered historical details of the era. “Satuday Night Live” and “Kids From the Hall” regulars appear as the people Woodward and Bernstein called “the President’s Men” (plus Rosemary Woods) and as Woodward and Bernstein themselves. All are terrific, and the under- appreciated Saul Rubinek is a stand-out as Henry Kissinger, far smarter than the people around him but so needy that he will try to persuade even the girls to agree with him. And Dan Hedaya, the only man in America with a five-o’clock shadow heavier than that of the real Richard Nixon, is sensational, needy, paranoid, and, in an hilarious dream sequence, positively endearing.

Some teens will enjoy it, even without a grounding in the history, but they will enjoy it more if they watch “All the President’s Men” first (Bruce McCulloch does a fine job parodying not just Carl Bernstein but also Dustin Hoffman playing Carl Bernstein). Parents should know that the explitives are not deleted and there is some very strong language, including puns relating to the President’s first name and a whispered explanation of the original meaning of “Deep Throat.” Betsy’s brother is a heavy drug user who is perpetually stoned, and some of his marijuana makes its way into the cookies the girls make for the President. Families will want to discuss the real events underlying the Watergate scandal and the impact it has had on the way we see the Presidency and the way the media covers the Presidents.

Video tip: This movie is reminiscient of the best movie ever about two girls with a crush on an impossible object: “The World of Henry Orient.” A funny and insightful glimpse into the stage of life where we rehearse our emotions by fixing on the unattainable, it is well worth watching. I noticed that “Dick” shares one important prop with “Henry Orient,” the super-modern one-piece telephone, and suspected that it was an homage to a classic film.

An evil and destructive spirit named Hexxus (voice of Tim Curry) is imprisoned in a tree by Magi, the leader of the fairies, who believes that all humans have been destroyed. Many years later, as Magi is teaching Crysta, her apprentice (voice of Samantha Mathis), they find that the humans have returned, and are cutting down all the trees. Crysta shrinks one of the humans, a young man named Zak, to save him from being hit by a falling tree, and teaches him about the importance of preserving the forest.

Highlights include Robin Williams as the aptly named “Batty Koda,” and gravel-voiced rapper Ton Loc as a Goanna lizard singing “If I’m Goanna Eat Somebody, It Might as Well Be You.”

There are some very scary moments and the magic characters may distract kids from the lesson about environmental conservation, but it does provide a good opportunity for discussions that may help in increasing sensitivity to environmental concerns.

Rob Gordon (Jon Cusack) asks the audience, “Do I listen to pop music because I was miserable, or am I miserable because I listen to pop music?” Rob spends more time talking to us than he does to any of the other characters in the movie, which is part of the problem. His candor and charm, both considerable, have allowed him to carry his adolescence through his 20’s, and he is much more comfortable concocting the definitive list of the best side-one, track-one songs ever than he is thinking about, say the definitive list of worthwhile things to do with his life. As his girlfriend Laura (Iben Hjejle) moves out of his apartment, he begins to think that maybe it isn’t enough just to like the right stuff. Maybe what matters is what you are like, not just what you do like.

Rob owns the least commercial enterprise possible, a vintage record store called “Classic Vinyl.” Only the two hopeless guys who work for him (Jack Black and Jerry Maguire’s Todd Luiso — both superb) make him feel like a grown-up by comparison. They sit around all day, getting rid of potential customers who are just not cool enough to be allowed to buy their records, endlessly ranking everything in the world and seeing the whole world as one big chance to measure everything. The death of one character prompts them to devise a “top five songs about death” list. They hyper-critically rate everything except for their own sorry lives.

Laura’s departure of course prompts Rob to make a list of his five worst break-ups, which allows him to comfort himself that she is not even on the list. But as he tracks down the five on the list to see if he can figure out what went wrong, he begins to admit to himself that he is deeply wounded, and not just because he feels threatened and competitive at the thought of her new love interest (a hilarious cameo by Tim Robbins). He has to allow himself to understand that “fantasies always seem really great because there aren’t any problems,” but that he needs to move on to reality. And he has to allow himself to be a little less self-obsessed. He realizes that he just might be on someone else’s list of the five worst heart-breaks and that it is actually not very likely that a music superstar will show up to give him advice. Fortunately, the “professional appreciator” is wise enough to see how special Laura is, and that he can not just “create a sketch of a decent, sensitive guy;” he can actually become one.

Parents should know that this movie has very strong R-rated material, including explicit sexual references and sex for reasons other than intimacy (one-night stand just for the sex, sex to numb sad feelings). Characters drink and smoke a lot. Parents whose teens see this movie might want to see it, too, to talk with them about the way people change as they grow up.

Families who enjoy this movie will also enjoy some of Cusack’s other performances, including Say Anything and The Sure Thing.
