The Upside: Patty Jenkins was previously scheduled to direct Thor 2, until plans between Marvel Studios and the Monster director hit a snag. However, the fact that she was attached to the project shows that she may have the credibility to take on a major motion picture.
The Downside: The details of the Thor dispute are still unclear. Her IMDB.com resume notes that Jenkins has directed episodes of Arrested Development, Entourage and The Killing but her biggest work to date is Monster, which likely won't prepare Jenkins for working on a highly-anticipated big-budget blockbuster.
The Verdict: Marvel's original support for Jenkins shows that she might be ready to helm a blockbuster. If the break-up between Jenkins and the studio was mutual, she could be the perfect choice to take on the complex characters and emotions in this series of books.
