Two Hollywood heavyweights are returning to the bigscreen next year in sci-fi fashion.

Tom Cruise toplines "Tron" director Joseph Kosinski's latest, "Oblivion," from Universal Pictures while Will Smith pairs with helmer M. Night Shyamalan on Columbia's futuristic saga "After Earth."

Both trailers are expected to run heavily this holiday season. (Watch below)

The question is...which looks better?

"Oblivion" trailer:

Next summer, the Enterprise crew will step away from the light and venture "Into Darkness."

Directed by J.J. Abrams and starring Chris Pine, Zachary Quinto and newcomer Benjamin Cumberbatch, Paramount's "Star Trek" follow-up tells the story of a evil, new presence in the Star Trek galaxy. Cumberbatch, who highlights most of the sci-fi tentpole's initial teaser, is rumored to play the villain Khan in the pic although neither Abrams nor the studio have confirmed the identiy of his character.

Alice Eve also makes her Star Trek debut, playing a character new to the canon (and a possible love interest of Captain Kirk).

Set for release May 17, 2013 and produced by Bad Robot, "Star Trek: Into the Darkness" was written by Damon Lindelof, Roberto Ortiz and Alex Kurtzman.
