Harrison Ford has attached himself to play Wyatt Earp in "Black Hats," based on the Max Allan Collins novel. The book is described as follows: A brilliant, original thriller that re-creates an exciting and dangerous time in American history and brings together two storied and feared crime legends. The Prohibition era has just begun, the Wild West a fading memory, and Wyatt Earp is making ends meet as a detective in Los Angeles. To help the late Doc Holliday's son, Wyatt goes east, where his onetime deputy, Bat Masterson, is New York's top sportswriter. Wyatt and Masterson face a showdown with a new breed of badmen—mobsters led by Brooklyn's brutal young Al Capone, in a takeover of young Holliday's hot new speakeasy. As the '20s (and machine guns) roar, the lawless lawmen enter a glittering world of showgirls and cafe society, of gangsters and gamblers, where their legends may even end as Scarface Al's begins.
