Aaron: (Commenting on the different directors for the X-Men series) You know they're both very different people and they both bring something unique to the project that they work on. The thing I really enjoyed about working with Brett is that the man is the Energizer Bunny. I mean, he just does not run out of energy. He's constantly on. When he comes in, he's thrilled to be on set. He's just very excited about life in general. That kind of positive energy on set really helps you out.
