The Thor sequel, which previously had Kenneth Branagh (the first film’s director) walk off due to scheduling conflicts, and then had Monster director Patty Jenkins attached, is once again lacking a director. Patty Jenkins has withdrawn from the project, reportedly due to “creative differences”, though she still wants to direct a superhero movie someday.
At this point, the project is starting to look like it’s not just director-less, but directionless. It’s supposed to land in theatres in November 2013, with filming to start this coming September. They’ve got time to get a director attached and get everything sorted out, but two changes in short order aren’t an encouraging sign.
