Most would probably agree the fourth season of Arrested Development was shaky, but it was clearly hurt by the show trying to work around the star's schedules. It did have enough good moments, suggesting there might be reason to come back though.
And it looks like it is finally happening. Speaking to The Wrap, executive producer Brian Grazer said that the show was really close to getting production going and crucially, all the cast had agreed to return. He said:
I think we're really close to pulling it off finally. All of the actors have agreed to do it and I think they've agreed to their compensation structure. That's been the hardest–it's all hard…But it should be happening soon.
I want another good season of Arrested development, and you miss all the shots you don't take. Hopefully the characters are all in one place this time though. I really hope this does come to fruition very soon.
