full_context: Document 1: Moe Greene: Morris "Moe" Greene is a fictional character appearing in Mario Puzo's 1969 novel "The Godfather" and the 1972 movie of the same name. 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.
Document 2: Cleaver (The Sopranos): Cleaver is a metafictional film within a TV-series that serves as an important plot element toward the end of the HBO television drama series "The Sopranos". Although very little film material is actually shown in the series, its planning and development are discussed at large throughout multiple seasons of the show. The extent to which Sopranos character Christopher Moltisanti mixes confidential and personal information about the Soprano mob family into the story elements of Cleaver is the focal point throughout its development. After the project eventually materializes, Cleaver can be categorized as a direct-to-DVD mafia-slasher film, described alternately as ""Saw" meets "the Godfather II"", ""the Ring" meets "The Godfather"", and "a story about a young man who goes to pieces and then manages to pull himself together again". Several characters are credited for their involvement in the project. The screenplay was written by J. T. Dolan based on a story by Christopher Moltisanti, directed by Morgan Yam and produced by Carmine Lupertazzi, Jr. and Moltisanti. The film starred Jonathan LaPaglia as Michael "the Cleaver" and Daniel Baldwin as mob boss Salvatore ("Sally Boy"). Also starring as Sally-boy's key advisors are George Pogatsia as Frankie and Lenny Ligotti as Nicky. Moltisanti and Lupertazzi initially attempts to recruit Ben Kingsley to fill the role of the mafia don in "Luxury Lounge (6x07)," but Kingsley eventually turns down the part.
