Once upon a time, before Twilight (the filming, anyway) and The Social Network, Kristen Stewart and Jesse Eisenberg starred in a lovely indie movie called Adventureland. Now they're running it back — except instead of a wistful movie about an amusement park, they are going to co-star in a stoner action comedy written by the Chronicle guy. Oh, and they're dating in this one. From the beginning. Congrats, Jesse Eisenberg.
