Actor Sylvester Stallone is reportedly in talks to portray real-life hitman Greg Scarpa in a new biopic.

If the Rambo star signs on for the film it will reunite him with Rocky producer Irwin Winkler and The Expendables producer Avi Lerner.

The movie centres on Scarpa's time as a Federal Bureau of Investigation (Fbi) informer.

Screenwriter Nick Pileggi tells the New York Post, "It's a fabulous story. Stallone is interested. He likes the script."
