Jude Law fans, rejoice: He'll appear in six films before New Year's, including a sly cameo as Errol Flynn in Martin Scorsese's ''The Aviator'' (Dec. 17). Leonardo DiCaprio stars as billionaire Howard Hughes, who charms Katharine Hepburn (Cate Blanchett), Ava Gardner (Kate Beckinsale), and Jean Harlow (Gwen Stefani). Sound fun? It's just one of the treats that Hollywood has in store for you this fall.
