It's official. Sylvester Stallone will return as John Rambo in "Rambo IV."

Production is set to begin once filming on "Rocky Balboa" wraps. Although the script hasn't yet been finalized, the story will have Rambo return to action when a young girl is kidnapped. Producer, Ben Nedivi of Millennium Films, said that "Rambo IV" will "recapture the rawness of "First Blood."

The first three Rambo films grossed over $600 million worldwide.
