The film, which will see Stallone return as the no-nonsense Green Beret, will shoot in Bulgaria, with filming locations in India and America to follow, according to top movie news website MovieHole.net.
In the new movie, Stallone's part Navajo Indian character has to take on white supremacists in America when his family comes under attack from them.
Nu Image/Millennium Films chairman Avi Lerner insists if Rambo IV is a success, and he's convinced it will be, there will be more Rambo films.
He says, "Stallone is one of the smartest guys I know. It's a franchise. If number four works, then you have a number five."
