R is a young man with an existential crisis – he is a zombie.  He shuffles through an America destroyed by war, social collapse, and the mindless hunger of his undead comrades, but he craves something more than blood and brains.  He can speak just a few grunted syllables, but his inner life is deep, full of wonder and longing.  He has no memories, no identity, and no pulse, but he has dreams.  After experiencing a teenage boy’s memories while consuming his brain, R makes an unexpected choice that begins a tense, awkward, and strangely sweet relationship with the victim’s human girlfriend.  Julie is a blast of color in the dreary and gray landscape that surrounds R.  His decision to protect her will transform not only R but also his fellow Dead, and perhaps their whole lifeless world.  Scary, funny, and surprisingly poignant, WARM BODIES is about being alive, being dead, and the blurry line in between.

The film stars Nicholas Hoult, Teresa Palmer, Dave Franco, and Rob Corddry.  It will go up against the political comedy Dog Fight starring Will Ferrell and Zach Galifianakis.

Sinister stars Ethan Hawke a journalist who moves his family from corner to corner so as to get the skinny on gruesome murders that he then adapts into books. As the story goes, Hawke and co. move into a house where an entire family was murdered, only to find said footage which lets them in on what really happened.  The movie will face off against the thriller Premium Rush starring Joseph Gordon-Levitt and Michael Shannon.

Now You See Me centers on a group of magicians that pulls off bank heists in the middle of their bewildering performances.  The movie stars Jesse Eisenberg, Wood Harrelson, Mark Ruffalo, Morgan Freeman, Isla Fischer, Dave Franco, and Melanie Laurent.  Now You See Me will have a tough weekend (especially for January) as it faces the 3D re-release of Monsters, Inc. and Arnold Schwarzenegger's comeback film The Last Stand.

We now have a brief logline for Red 2: "The sequel to the action-comedy hit RED, which reunites our team of retired CIA operatives as they use their old-school style to take on a new set of enemies all across Europe." The writers of the first film, Jon and Erich Hoeber, were brought back to pen the sequel.  Producer Lorenzo di Bonaventura said back in June that they're trying to figure out which cast members to bring back.

Here's the synopsis for Orson Scott Card's Ender's Game:

In order to develop a secure defense against a hostile alien race’s next attack, government agencies breed child geniuses and train them as soldiers. A brilliant young boy, Andrew “Ender” Wiggin lives with his kind but distant parents, his sadistic brother Peter, and the person he loves more than anyone else, his sister Valentine. Peter and Valentine were candidates for the soldier-training program but didn’t make the cut—young Ender is the Wiggin drafted to the orbiting Battle School for rigorous military training.

Ender’s skills make him a leader in school and respected in the Battle Room, where children play at mock battles in zero gravity. Yet growing up in an artificial community of young soldiers Ender suffers greatly from isolation, rivalry from his peers, pressure from the adult teachers, and an unsettling fear of the alien invaders. His psychological battles include loneliness, fear that he is becoming like the cruel brother he remembers, and fanning the flames of devotion to his beloved sister.

Is Ender the general Earth needs? But Ender is not the only result of the genetic experiments. The war with the Buggers has been raging for a hundred years, and the quest for the perfect general has been underway for almost as long. Ender’s two older siblings are every bit as unusual as he is, but in very different ways. Between the three of them lie the abilities to remake a world. If, that is, the world survives.

Roberto Orci and Alex Kurtzman are producing.  Click here for what they had to tell Steve about the film back in June.  Ender's Game shares its weekend with David Dobkin's Arthur & Lancelot.

Finally, Step Up 4 will be in 3D and star Kathryn McCormick, Ryan Guzman, and Stephen Boss.  Here's the logline: "Emily, the daughter of a wealthy businessman, arrives in Miami with aspirations of becoming a professional dancer, but soon falls in love with Sean, a young man who leads a dance crew in elaborate, cutting-edge flash mobs." Step Up 4 will open alongside the comedy Neighborhood Watch starring Ben Stiller and Vince Vaughn.
