Freddy and Jason, Alien and Predator, that time Urkel was on Step by Step: if there's one thing audiences will tolerate, it's pointless crossovers. So how about a Pineapple Express/Superbad crossover, even though Seth Rogen is in both films playing different roles, which would probably lead to some kind of confusing, Tommy Westphall-style paradox? Well, regardless, James Franco says it might be happening. From MTV:
Even before 'Superbad' came out, I think the studio was trying to get [ Seth Rogen and Evan Goldberg ] to write a sequel, but they really didn't want to write a sequel. I guess the kids would go to college or something like that [that was the studio's idea]," Franco said. "And so, an answer to that was to do a 'Superbad'/'Pineapple Express' crossover, an unprecedented crossover movie with two directors, Greg Motolla and David Gordon Green, each directing half of the movie and somehow these characters get together, which doesn't make sense at all, but could work."
