In a marginally related story, Star Wars: Episode VII may need a new director. Badass Digest is hearing rumors from multiple sources that Abrams is close to dropping out of the highly anticipated sequel.

True or not. The fact that there are even rumours of discord are a concern.

Don't make life difficult for JJ Disney. Have faith that you picked the right dude for the gig and let him get on with it. Sign the outgoing cheques and then cash the larger incoming ones when it gets released... simple.
