There's an old Hollywood adage: "when you're planning a sequel to a movie that hasn't come out yet, the last person you tell is the movie's director." So it's no surprise that the news about Thor 2 already being in development is truly news to director Kenneth Branagh.

Recently, Marvel Head Kevin Feige confirmed there would be sequels to both Thor and Captain America. In an interview, Branagh was asked about the announcement, and he had no idea there was an announcement. I guess he doesn't subscribe to The Daily Bugle. Here was Branagh's response:
"...I’m thrilled they’re that confident. I shall wait for the audience to tell us whether there should be a second one, and then if that’s a nice conversation to be had between all of us, that’d be thrilling. But I’ve got too much Irish superstitious blood in me to assume that Thor 2 will happen. But if Marvel says so, then I guess it must be true.”

Wow, someone wants to wait and see if a movie's successful before working on the sequel. That's so crazy, it just might work. Or rather, it's not crazy at all, and it's how things should be. You can tell Branagh how many Thor-s you want by going, or not going, to see the movie on May 6th. (Movieline)
