There were a lot of rumors that Marvel was looking at Brad Pitt to star in THOR for director Kenneth Branagh. But based on a recent casting description for the film, Brad Pitt doesn't seem to fit that description at all. Coming Attractions unearthed a casting notice for THOR and this is what they're looking for in a main character: Male MUST BE MID-LATE 20'S and SIX FEET OR TALLER.
