Moe Greene
Morris "Moe" Greene is a fictional character appearing in Mario Puzo's 1969 novel The Godfather and movie. The character's name is a composite of real Las Vegas mobsters Moe Dalitz, or possibly Moe Sedway, and Gus Greenbaum. However, both Greene's character and personality are actually based on Bugsy Siegel: his affiliation with the mob in Los Angeles, his involvement in the development of Las Vegas, and his flamboyant tendencies. Greene is portrayed in the movie by Alex Rocco.
The Godfather
Moe Greene is introduced in The Godfather as a renowned Jewish mobster and former executioner for Murder Incorporated. He is credited with the development of gambling and entertainment in Las Vegas and bringing the interests of the most powerful organized crime organizations in America to Nevada. Greene is in business with Don Vito Corleone, who bankrolls the creation of Greene's first hotel-casino. In return, Greene takes the Don's son Fredo under his wing during the war between the Five Families in New York, due to the intervention of West Coast Don Anthony Molinari. Although Fredo is greatly influenced by both Greene and the city, family heir Michael Corleone disapproves of the effect it has on his brother, whom Greene reportedly chastised and slapped around in public.
