As the production of Roar involved lions, tigers, and other dangerous animals, it is unsurprising to learn that people were injured during the production. But 70 sounds like an exaggeration. In fact, one of the film’s stars, John Marshall, confirms the math is inaccurate. “Actually I think it was 72,” he says.

Most dramatically, the film’s director of photography Jan de Bont—later the director of Speed and Twister—needed 120 stitches after being essentially scalped by a lioness. “I got him on the way to the hospital, and I went into the office and said, ‘Okay, we need to get a DP,’” says John. “Because I figured that DP was not coming back. And he came back and finished the movie! I was amazed. Jan was a trooper.”

Principal photography on Roar started on October 1, 1976 at Santa Clarita, where most of the movie was filmed. By this point, the animal cast numbered 132 lions, tigers, leopards, cougars, and jaguars, as well as a 10,000-pound bull elephant named Timbo, which Marshall and Hedren acquired from an animal park in Canada. The shoot was scheduled to last six months but stretched to three years, thanks partly to periodic shutdowns as Noel Marshall hustled to finance a budget which ultimately ballooned to $17 million.
