Arguably the must see movie of 2004 (Kill Bill Vol. 2 is still the must-see for mosts), The Aviator boasts a star-studded cast and crew. Martin Scorsese (GoodFellas, Gangs of New York) is directing, and Leonardo DiCaprio, Jude Law, Alec Baldwin and John C. Reliy star. But that's not what's interesting. The roles of Jean Harlow, Ava Gardner, Katharine Hepburn and Lena Horn (which all actresses fought over including Oscar winners Nicole and Renee and Gwyneth and Halle) are given already. Gwen Stefani will make her big-screen debut as Jean, Cate will play Katherine, Kate (Beckinsale) will play Ava and Josie Maran might play Lena Horne.
