Humphrey Bogart, nicknamed Bogie, was an American actor. His performances in classic Hollywood cinema made him an American cultural icon. In 1999, the American Film Institute selected Bogart as the greatest male star of classic American cinema. His breakthrough came in High Sierra (1941), and he catapulted to stardom as the lead in John Huston's The Maltese Falcon (1941), considered one of the first great noir films. Bogart's private detectives, Sam Spade (in The Maltese Falcon) and Philip Marlowe (in 1946's The Big Sleep), became the models for detectives in other noir films. In 1947, he played a war hero in another noir, Dead Reckoning, tangled in a dangerous web of brutality and violence as he investigates his friend's murder, co-starring Lizabeth Scott. His first romantic lead role was a memorable one, as Rick Blaine, paired with Ingrid Bergman as Ilsa Lund in Casablanca (1942).
