Looking ahead, is there any update on Triplets [an in-development sequel to Twins that had Ivan Reitman attached to direct until his death last year]?
Jason Reitman fucked it up! Jason Reitman literally stopped the project when his father died. His father wanted to do it really badly. I wanted to do it really badly. Danny DeVito wanted to do it really badly. We had the financing. When his father passed away, Jason says, “I never liked the idea” and put a hold on it. I’m developing another movie with Danny; he’s so much fun to work with and so talented.
