Bryan Singer would be awful. His films are largely boring. Only X2 was fun and even that was off kilter. Kevin Smith would be too much of a fanboy just like JJ. Tim Burton would never work. I can't see HBC in the GFFA nor can I see Johnny Depp but whatever. Peter Jackson would be okay but he's been defined by the Tolkein movies. Why play in another person's sandbox? Guillermo is too---off. Honestly, I like the Brad Bird suggestion quite a bit. And if Christopher Nolan could shift his mindset to the GFFA, then he might be okay. But I think his movies are far too dense (in both good and bad ways) for it to work in Star Wars.
