"After Earth" (PG-13, 100 minutes, Sony): Will Smith fans who have been eagerly awaiting their hero's next rock 'em, sock 'em action adventure will have to wait a little bit longer. His character in "After Earth" spends most of the new sci-fi flick flat on his back, with two broken legs. Instead, the film -- directed by M. Night Shyamalan from a script by Shyamalan and Gary Whitta ("The Book of Eli") -- is a vehicle for Smith's son, Jaden. The 14-year-old Smith is the real hero of "After Earth," a sentimental father-and-son melodrama set in a post-apocalyptic future in which humans have evacuated an uninhabitable Earth for a distant planet. When their spacecraft crash-lands on Earth, Gen. Cypher Raige (Smith senior) and his son Kitai (Smith junior) must navigate 100 kilometers of treacherous terrain filled with carnivorous beasts to locate the electronic distress beacon that will save them. The bad news: Dad was seriously injured in the crash, and Kitai is young, impulsive and untested. The good news? Kitai's form-fitting space suit -- which looks like steampunk long johns outfitted with a bicycle-seat-shaped backpack -- is made with high-tech "smart fabric." Contains some violence, blood and gore. Extras include "A Father's Legacy" featurette with Will and Jaden Smith on- and off-screen; an on-location and "The Nature of the Future" featurettes.
"The Hangover Part III" (R, 100 minutes, Warner): After "The Hangover Part II," more than one critic took filmmaker Todd Phillips to task for too slavishly following the first movie's winning formula. For a story so heavily dependent on the element of surprise, why couldn't he nudge things in a slightly different direction? With "The Hangover Part III," he has taken that advice to heart. And that's the problem. "Part III" is such a departure from the franchise that there's not even a hangover. To the contrary, the action here is precipitated by an intervention. It starts on a road trip to Arizona, where deranged man-child Alan (Zach Galifianakis) -- whose careless drug dispensing gets everything going so horribly wrong in the first two movies -- is being taken to a rehab facility by his reluctant friends Phil (Bradley Cooper), Stu (Ed Helms) and Doug (Justin Bartha). While en route, the four are ambushed by thugs working for the gangster Marshall (John Goodman), who wants to exploit the men's connections to Leslie Chow (Ken Jeong) to retrieve some stolen gold. Contains obscenity, nudity, violence, crude humor, offensive ethnic stereotypes and mistreatment of animals. Extras include outtakes, extended scenes, "Replacing Zach: The Secret Auditions," "Inside Focus: The Real Chow" and three making-of featurettes, including "Zach Galifianakis in His Own Words."
"Much Ado About Nothing" (PG-13, 109 minutes, Lionsgate): The feints, schemes, deceptions and setbacks that inevitably lead to love make for a divertingly merry war in Joss Whedon's larky adaptation of Shakespeare's play. Transposing the manners and verbal flourishes of Elizabethan England to 21st-century Santa Monica, Calif., Whedon finds unexpected meaning in this famously saucy "skirmish of wit," the opposites-attract story upon which myriad modern-day rom-coms have sprung. Not only does the spiky verbal sparring between would-be lovers Beatrice and Benedick still crackle with convincing sting and verve, but Shakespeare also turns out to have plenty to say about an era when, more than ever, someone is more apt to be destroyed by fast-moving rumors and strategic leaks than by an act of brute physical aggression. As the story opens, the brave and accomplished officer Benedick (Alexis Denisof) is just arriving at the home of governor Leonato, whose daughter Hero soon comes into the sights of Benedick's comrade-in-arms, Claudio. While Benedick is being lionized, Hero's sharp-tongued cousin Beatrice (Amy Acker) is having none of it. With "Much Ado About Nothing," Whedon has crafted an endearing bagatelle, made with equal parts brio and love, ambition and pared-down modesty.
"The Purge" (R, 85 minutes, Universal): A stock home-invasion thriller made moderately more interesting by a thin veneer of pop psychology, "The Purge" asks us to believe that, in nine short years, American society will have become so depraved that our government will grant us one night a year to indulge our inner Neanderthals with impunity. Set in 2022 during an annual 12-hour event known as Purge Night, the movie follows the efforts of a suburban family to fight off a pack of masked killers who are taking advantage of the evening's temporary suspension of law and order. The Purge allows citizens to blow off steam by doing pretty much anything they want to each other and get off scot-free, a setup that doesn't make much sense.
Writer-director James DeMonaco does wring a certain macabre humor out of the premise as the film opens with a man sharpening a giant blade on his neatly manicured front lawn, for all the cul-de-sac to see. But the heroes of "The Purge" aren't like that. Salesman James Sandin and his wife, Mary (Ethan Hawke and Lena Headey), are decent law-abiders, living in a tidy McMansion that has been fortified with the same state-of-the-art security systems that he has sold to all his neighbors. As Purge Night descends on their home -- along with steel shutters -- James and Mary curl up with a small arsenal of guns for what they hope will be just another quiet night in front of their glowing security monitors, with their kids tucked safely into bed. Contains bloody violence and cruelty. Extra: making-of featurette.
