DiCaprio as Hughes was one of the best performances of 2004. If Ray had come out another year, DiCaprio probably would have won BEST ACTOR for The Aviator. DiCaprio is one of the best actors of his generation... he would instantly bring credibility to a Part IV, and since he and Scorcesse are best buds, might even cause Marty to think about helming a Part IV.

Ah, a boy can dream, can't he? Leo wouldn't touch Part IV with a ten foot pole, especially after the disaster that was TGR.
