If you want a journalistic recounting of Edward Snowden's paradigm-altering PRISM leak, you should definitely check out last year's documentary, Citizenfour. If you want Oliver Stone's more, er, colorful version, here is a trailer for Snowden. It's always hard to dramatize what often amounts to a lot of very fast typing, and based on this brief look, Snowden hasn't discovered a non-awkward way to do so. And there's clearly a heaping helping of artistic license at play; as entertaining as the trailer's Rubik's Cube caper seems to be, Snowden (Joseph Gordon-Levitt, taking his voice down a register here) snuck his secrets out on a boring ol' thumb drive. Fortunately, the real story is packed with enough drama that Stone should have plenty of chances to hew close to it after all.
