Last summer, we saw a lot of Jake Gyllenhaal in London with his girlfriend Reese Witherspoon as he worked on Prince of Persia: The Sands of Time in the UK. He stars in the movie alongside Gemma Arterton, Alfred Molina and Ben Kingsley, and the trailer has just been released! It's not out until May 2010, but check out this action packed preview and let me know — do you think you'll see it, or skip it?
