Leonardo DiCaprio could be teaming up again with Martin Scorsese for The Wolf Of Wall Street.
The news was revealed by Jordan Belfort, whose 2008 memoir will be given the big-screen treatment by Sopranos scriptwriter Terry Winter.
"After almost four years in development, I can't begin to tell you how thrilled I am to finally be working with Leo and Marty on this - they're the ultimate Dream Team, and it was definitely worth the wait," he told the Hollywood Reporter.
Ridley Scott is tipped to direct, while Leonardo's production company and Martin are producing the film together. More details are expected to be revealed at the Cannes Film Festival in May.
The Wolf Of Wall Street follows Jordan's fast-dealing, drug-and-sex-drenched ways in the 1990s through the halls of Wall Street, which eventually led to him serving time in jail for offences related to stock market manipulation.
Martin is finishing off Hugo Cabret, starring Chloe Moretz, while Leonardo - who has worked on four films with the acclaimed filmmaker - is shooting J Edgar, directed by Clint Eastwood.
