Actor Sylvester Stallone, known for playing heroes like John Rambo and Rocky Balboa, is now considering playing a villain - Greg Scarpa, a notorious mob boss. The film's screenplay by Nick Pileggi, who wrote ‘Goodfellas’ and ‘Casino’, will highlight Scarpa’s involvement in 20 murders and focus on his career, reports New York Post newspaper's Page Six column. Pileggi said “It’s a fabulous story. Stallone is interested. He likes the script.” Irwin Winkler, of ‘Rocky’ fame, will produce with Avi Lerner, who produced ‘The Expendables’ and its sequels.
