Just to keep people appraised of the sci-fi movies that will be hitting theaters this year, I’ve assembled some of the trailers for the genre’s most anticipated films. There are a few high profile films left out of this roundup, including Snowpiercer, Riddick, Ender’s Game, Gravity and Elysium, but that’s because they don’t have trailers at the moment and there’s nothing I can do about that short of sweding the trailers for them. So, for now, these are the trailers for the heavy hitters of sci-fi in 2013.
