Sylvester Stallone working on his own biopic

Action star Sylvester Stallone is making plans to bring his own life story to the big screen, according to his mother Jackie.

The 'Rocky' star has written and directed a number of projects throughout the years, and he has now focused his attention on making a movie about his upbringing and lengthy career in Hollywood, reported Daily Express.

"Sylvester is doing the story of his life, his own biog(raphy). He's got Rambo V to film and he'll be going to Budapest to begin the Expendables 4 - so he's filming his biopic in between," Jackie said.
