A few days ago, we brought you a TRON: Legacy billboard featuring star Garrett Hedlund rocking frosted tips and wielding a light disc.  It was an alright ad.  Tonight, there's a new billboard with Olivia Wilde rocking a bob hairstyle and wielding a light disc.  I like this ad a whole lot more.  It's funny how that happens when all you've done is replace the actor and the hairstyle.  Oh, and I find Wilde incredible attractive.  That also might have something to do with my appreciation of this billboard.

For those who don't know, Disney has bought the billboard at Santa Monica/Westwood in Los Angeles for all of 2010 and there's a new image each month.   Hit the jump to check out the full image.  TRON: Legacy opens on December 17th.  It will also be dominating Comic-Con next week so be on the lookout for our coverage.

Here’s the official synopsis for TRON: Legacy:

TRON is a 3D high-tech adventure set in a digital world that’s unlike anything ever captured on the big screen. Sam Flynn (GARRETT HEDLUND), the tech-savvy 27-year-old son of Kevin Flynn (JEFF BRIDGES), looks into his father’s disappearance and finds himself pulled into the same world of fierce programs and gladiatorial games where his father has been living for 25 years. Along with Kevin’s loyal confidant (OLIVIA WILDE), father and son embark on a life-and-death journey across a visually-stunning cyber universe that has become far more advanced and exceedingly dangerous.
