5. Crank
The Movie: The final chapter in Chev Chelios' crusade, as he now has to contend with being a severely-disfigured burns victim, and having his heart replaced by a hamster wheel (or something)...in 3D.
Is It Happening?: Hard to say. The original film was a breakout cult hit at the box office, whereas the sequel, High Voltage, pulled in disappointing returns on a significantly higher budget. Amy Smart has said that it's been discussed in the past, and was the first to suggest - quite brilliantly, in fact - that it would make sense for a film as outrageous and visually bold as Crank to be released in 3D. Directors Neveldine/Taylor seem up for it, but it's likely just a case of getting the money in place, and also assuming that Jason Statham would be onboard for another one.
Likelihood: Perhaps with a slightly scaled back budget, this one might actually happen.
