Less sequels, and more films made in the same vein is what I'm after.
And in that regard, Hustle has a prequel! Look up Shoalin Soccer. It's not as good as Hustle, but it's in the film's league, and made by the same people.
Has the sequel ever officially been called off? Odekirk had an update saying he was still working on it a few years ago. Which could have been like 10 years ago at this point. But still.
He was writing a Stretch Armstrong movie back when all those random toy films (GI Joe, Battleship, etc.) were getting greenlit after Transformers blew up. Which is both the greatest and worst idea of all time.
