2013 movie preview: 'Hunger Games: Catching Fire,' 'Star Trek Into Darkness,' 'Iron Man 3' and more big movies

What's big at the movies in 2013? Pretty much exactly what was big in 2012: sequels, reboots, and heroic characters with funny names like Katniss Everdeen, Bilbo Baggins and Channing Tatum.

We've rounded up 23 big movies -- from March's "Oz: The Great and Powerful" to December's "Anchorman: The Legend Continues" -- to watch for in the year ahead. Not all of them will be good, but they'll all be a big deal for one reason or another.

There are superheroes new (Superman's return in "Man of Steel") and old (welcome back Iron Man, Thor and Wolverine), reboots of beloved characters ("The Lone Ranger"), and a sequel to a beloved reboot ("Star Trek Into Darkness").

And there are some unexpected twists and turns, like Joss Whedon tackling Shakespeare ("Much Ado About Nothing"), Brad Pitt battling zombies ("World War Z") and double doses of Leonardo DiCaprio ("The Great Gatsby," "The Wolf of Wall Street") and Sandra Bullock ("The Heat," "Gravity").

Check out our 2013 movie preview gallery for a sneak peek at all of these, and more. Then let us know what you're looking forward to seeing at the movies in 2013.
