John Thompson, action film megaproducer and head of production at Millennium Films, died Tuesday after a battle with leukemia, the studio announced. He was 71.

Thompson had worked at Millennium since its founding in 1996, and was a major driving force behind the studio’s action movie-oriented slate, working with stars like Sylvester Stallone and Jason Statham. His credits include the 2008 revival of “Rambo,” the “Expendables” trilogy, and the “Fallen” trilogy that started with “Olympus Has Fallen” and “London Has Fallen” and will continue with “Angel Has Fallen.” The latter is tentatively slated for release later this year and on which Thompson will be posthumously credited.

“John Thompson was my friend and collaborator for 38 years,” Millennium exec Boaz Davidson said in a statement. “He was a brilliant producer, full of vision and creativity. As our head of production, he was loved and respected by the whole Millennium family, by the crews and by the talent. John’s passing is a colossal personal loss for all of us.”

Thompson is survived by his wife, Tatiana, and three children.
