My picks:

1. Steven Spielberg (not going to happen though)

2. Brad Bird (probably won't happen either, Disney would rather have him for Incredibles 2)

3. Edgar Wright

4. Matthew Vaughn

5. Rian Johnson

And, well maybe that's it.

Christopher Nolan, Neill Blomkamp, Guillermo Del Toro, or Alfonso Cuaron would all do a fine, dare I say great job, but I doubt any of them would do it.

And there's a chance that Andrew Stanton, Joe Johnston, David Koepp, Jon Favreau, Rupert Wyatt, Duncan Jones, the Russo Brothers, Alan Taylor, or Joe Cornish could work well.
