Sylvester Stallone, Bear Grylls and Endemol Shine North America have established a production partnership with plans to create high-adrenaline series.

The two adventure titans are teaming up to create “genre-bending” adventure series.

Stallone will exec produce via his Balboa Productions (along with Kourosh Taj, his head of unscripted development and Carrie Keagan), while Grylls will exec produce for his Natural Studios (which is a joint venture with Banijay, alongside his co-CEO Delbert Shoopman). Sharon Levy and DJ Nurre will exec produce for Endemol Shine North America.

Balboa Productions is behind Taylor Sheridan’s Stallone-fronted Paramount+ series Tulsa King as well as feature films Samaritan and Rambo: Last Blood as well as DAZN feature doc One Night: Joshua vs. Ruiz.

Stallone said, “My goal has always been to push the envelope not only in life, but in all of my creative endeavors. Nothing is more satisfying than mixing the improbable with the incredible and creating the unforgettable. What we have planned is epic, beautiful and game-changing and I can’t wait for everyone to experience it.”

Grylls said, “It’s a complete honour to be working with the whole team at Balboa Productions. As possibly the most iconic face in the action space, Sly has long brought an injection of adrenaline to his roles and we envisage that energy being channeled into our development.”
