MISSOULA, Mont. (AP) — Actor and former California Gov. Arnold Schwarzenegger is out on the fire lines in western Montana filming a documentary on climate change. Fire Information Officer Nancy Guerrero says a film crew is profiling the Snake River Hotshots as they work on the lines of the 9.6-square-mile West Mullan Fire burning north of the town of Superior.

Members of the National Interagency Fire Center are also on hand. Schwarzenegger had breakfast with the fire crews Monday morning before heading out to the lines. KECI-TV reports  Schwarzenegger is the executive producer of the documentary, which is looking at climate change and how it impacts the fire season. It is scheduled to be aired on Showtime. The Snake River Hotshots are based in Pocatello, Idaho.
