Here’s a spooky story: a talented storyteller mesmerizes his audience and then loses his way in a thicket of self-regard so that no matter how hard he tries, each of the stories he tells becomes less powerful than the one before.

M. Night Shyamalan is one of the most talented film-makers working today. But he seems to be running out of ideas. He still knows how to use a camera brilliantly and he is still a master of images that are disturbing in an intriguing way. But so much of this movie seem greatest hits cut and pasted from his other, better films, as generic as the title (anyone else here humming the Supremes song?). There is a train as in “Unbreakable.” There is a scene in a schoolroom as in “The Sixth Sense.” A child is important to the story as in “The Sixth Sense” and “Signs.” Like “Signs” there is a scary scene with characters trapped in a beautiful old house in a remote location.

“There appears to be an event happening.” All at once, without warning, people in New York City’s Central park become disoriented and then self-destructive. They begin to kill themselves. Bodies come hurtling from the girders of a construction project. A cop pulls out his gun and kills himself. Others grab the gun lying near his body to shoot themselves with the remaining bullets. Have terrorists released toxins into the air? Is it some kind of alien attack? No one knows.

In Philadelphia, high school science teacher Elliot Moore (Mark Wahlberg) is called out of class. The students are being sent home. He and his best friend Julian (John Leguizamo), a math teacher, decide it will be safer away from the city. Julian’s wife is out of town but will meet up with them. Elliot’s slightly estranged wife Alma (Zooey Deschanel) comes along but insists on sitting alone. Then, in the middle of nowhere, the train stops. “We’ve lost contact,” the conductor tells them. “With whom?” “Everyone.”

Julian goes in search of his wife, leaving his shy daughter with Elliot. And so Elliot, Alma, and the little girl go on the run, not knowing anything about what it is they are running from or where they are running to.

Many of the individual scenes deliver. Shyamalan knows how to create an eerie mood and when to pepper the story with release, whether a gasp or a laugh. But there is some unintentional humor as Elliot and Alma pause to resolve their marital conflicts, natter about a mood ring, and Elliot tries to make conversation with a potted plastic plant. The talented Wahlberg and Deschanel do their best but cannot make much of an impression with cardboard characters and clunky exposition. Wahlberg manages some warmth now and then but Deschanel has little do to but open her eyes wide. Those blue eyes seem to be Shyamalan’s favorite special effect. The exposition is intrusively inserted and clumsily handled. And in the last half hour, just as things should be ramping up, all of the air rushes out like a stuck balloon. Shyamalan does not always have to deliver a twist, but he does have to deliver an ending better than this one.

Parents should know that this movie has a good deal of violence, some graphic, multiple suicides, shooting death of teenagers, mauling by an animal, some grisly images of wounds and dead bodies, disturbing themes including the deaths of hundreds of people, and brief strong language. There is a sexual joke and there are some mild references to infidelity.

Family discussion: Julian has to make a very difficult choice between protecting his wife and protecting his daughter. What were the reasons for the decision he made and do you agree? What other choices made by the people in this movie seemed right or wrong to you?

This week director Eric Brevig and producer-star Brendan Fraser (“That’s Fraser like razor”) answered questions about their new film, “Journey to the Center of the Earth 3D.” Unlike the earlier versions, including the 1959 George Pal version with Pat Boone and James Mason and a recent made-for-television movie starring Ric Schroeder, this is based on the Jules Verne book. Instead, it is the story of a modern-day scientist who searches for his brother, who discovered that Verne’s book was true.

The movie is a real thrill-ride with great stunts and effects and it was a blast to hear Brevig and Fraser talk about how it was made. In order to get the 3D effect, they have a special camera that shoots two separate movies, one for each eye. Essentially, they are projected together on screen (we got a sense of how tricky that was when they got it wrong three times before rebooting the system to get it right) and then when viewed with the special glasses, the audience gets a sense of depth and detail so distinct that — well, when the dinosaur drools, you’re going to feel like you need to wipe off your forehead.

Fraser good-naturedly answered questions — no, there will not be a sequel to “Encino Man” and yes, he does all his own stunts (he pointed out that the hanging off a cliff and getting burned stunts were left to the last day of shooting at the request of the insurance company). Brevig swore us all to secrecy when he confided that Fraser has one additional uncredited role in the film — he provides the warbling sounds for the adorable little glow-birds.

With its first self-financed production, Marvel has produced one of the best superhero movies ever made, pure popcorn pleasure for its special effects, its story, its villain, and its hero. Director Jon Favreau, star Robert Downey Jr. and a first-class screenplay mix electrifying action, a compelling drama, and top-notch performances. Plus there are the best robot-type characters since R2D2, C3PO, and Hewey, Dewey, and Louie.

Downey plays international weapons dealer/super-brain/playboy Tony Stark as a rock star. He is an industrialist who appears on the cover of Rolling Stone and dates cover girls. He has an answer for every possible question or criticism about the company he runs: “The day weapons are no longer needed to keep the peace I’ll start building beams for baby hospitals.” But he does not have an answer for himself. His own conflicts would haunt him if he would slow down for a moment to think about them. That moment comes when he is captured by jihadists on a sales tour of American armed forces in the Mideast, using his own weapons. Told to recreate his company’s most powerful weapon for them instead he creates something for himself. The mastermind of cutting edge technology reaches back to the oldest of old school combat and creates for himself a high-tech suit of armor so that he can escape. It becomes the first stage in what will transform him into Iron Man. And the more he is protected by his Iron Man suit, the more he begins to open up to himself and others about who he really is and take responsibility for the world he has helped to create.

Downey superbly conveys Stark’s vulnerability and brilliance. He makes every line of dialogue feel improvised and natural, a great counter to the over-the-top special effects and fight scenes. In this middle of this great big movie he gives a subtle performance that is every bit as compelling as the most jam-packed action footage. He evolves as the suit does, trying out new things, coming alive for the first time as he is encased in metal.

The themes of the story has some powerful resonance about America’s role in the world without being heavy-handed. There’s no time for it — everything moves quickly as Stark continues to develop his suit and is attacked by bad guys and good guys and, well, there’s another category I am not going to give away. There is strong support from Terrence Howard as Stark’s military contact and friend, Gwenyth Paltrow, who gives some snap to her role as the indispensable aide de camp, and Jeff Bridges (with his head shaved!) as Stark’s closest business associate. The visuals are bracing and powerful and the action scenes are fanboy heaven. Watch for quick cameos from director Favreau, fan Ghostface Killah, and Iron Man co-creator Stan Lee. But don’t get distracted. Downey is the literal heart of this movie, and like the appliance that keeps Stark alive, he is a power source whose potential seems limitless.

Andy and Larry Wachowski, the folks behind the Matrix trilogy, have taken the iconic but decidedly low-tech 1960’s Japanese cartoon character and put the pedal to the metal with dazzling effects and electrifying action. Do what Speed Racer does — put on your red socks and GO!

Even as a child, Speed Racer could only think of one thing, making cars go as fast as possible. Not surprising — he was surrounded by racing. The family business was race cars. His father (John Goodman) built them and his older brother drove them. When his brother is killed in a crash, Speed (Emile Hirsch) takes over. On and off the race track he battles the competition, even when they do not fight fairly. By his side are his parents, his little brother, his and his girlfriend Trixie (Christina Ricci, looking like a real-life version of an anime heroine with her enormous eyes).

The plot is pretty much the same as the cartoon series, meaning light-weight and a little incoherent. Basically, evil forces are trying to stop Speed from winning the race. The sections with the kid brother and his chimp are slow points for everyone over age 9 but it is all great fun, with a hero to believe in and visuals that are both reassuringly retro and stunningly innovative. Every wallpaper and fabric, each car, helmet, and racetrack is meticulously designed to evoke a mash-up between Speed’s Norman Rockwell-style, solidly heartland home and the souped-up super space age world outside. The Wachowskis re-invent the color wheel with reds and yellows that make fire engines and school buses seem pale.

The dialogue is pared down to essentials: “You think you can drive a car and change the world? It doesn’t work like that!” “Maybe not, but it’s the only thing I know how to do and I gotta do something.” The plot is no more significant (or confusing) than in the cartoon originals. All we need to know is that in the world of Speed Racer you can drive a car and change the world — if you drive it very, very fast.
