Channing Tatum doesn't really seem to have any interest in making a third 21 Jump Street movie, despite the huge success of the sequel which saw him and co-star Jonah Hill going to college.
Tatum is currently working on a sequel to Magic Mike, but will obviously only make a follow up if he feels it will work. He told USA Today:
"If we did a third one, it couldn't be in there. I feel like that would be a cop-out. College was the obvious next step for us. We had to go there. I don't know what the next step is after college. Do we go and take down Enron? Or the government in D.C.? I feel like it's all redundant. The big running joke of the second movie is this is just going to be bigger and (crappier) than the first time. I don't know if that joke works three times so we'll see."
There had been rumours that the next film could see the two lads going to medical school. Not bloody likely it seems.
