Which Rambo film did James Cameron co-write?

James Cameron co-wrote Rambo: First Blood Part II. The 1985 sequel brought John Rambo back to Vietnam, where he is assigned to photograph possible American prisoners of war. Cameron wrote an early screenplay draft before Sylvester Stallone revised the script and received shared screenplay credit.

Cameron was still an emerging filmmaker when he worked on the project. He was developing The Terminator at the same time and would later write and direct Aliens. His original draft was titled First Blood II: The Mission and reportedly emphasized the action elements, while Stallone shaped much of the final film's political and character material.

A common mix-up is confusing Cameron's screenplay credit with the film's story credit. Kevin Jarre received the story credit, while Stallone and Cameron were credited for the screenplay. George P. Cosmatos directed the finished movie, which became one of 1985's biggest global box-office successes.
