I can't even fathom how many movies, tv news shows, re-creations, and documentaries we're going to see about the JFK assassination as its 50th anniversary approaches in November. But this Paul Giamatti, Billy Bob Thornton, Marcia Gay Harden, Zac Efron movie probably won't be the worst of the lot. Hard to tell from the trailer, but it looks pretty good, given that we all pretty much know the story already.
