With only Michael Cera holding out on the cast, the ball apparently is still moving forward on an Arrested Development movie.
Series creator Mitch Hurwitz was in an interview when the topic came up and he is asked about the plot.
Do you wanna know what this film will be about? Do you really wanna know? Because it’s beyond crazy — it’s so freakin’ out there you might need to sit (or lay) down, preferably in a relaxed position with one leg (left?) slightly bent. Ready? Here’s what Hurwitz and the gang have planned plot-wise for the film: “We have a story, which is basically Valkyrie meets Hotel for Dogs.”
So from that I have managed to gather that he got the interviewer literally leaning off the edge of his seat and then throws out something that sounds like news until your brain digests it and you realize what he has said.
Nothing.
So aside from waiting on Michael Cera to sign on (everyone else has) and firming up the deal “more or less in place” we honestly know nothing more about this movie.
