It's not easy playing sidekick to "The Lone Ranger," as Johnny Depp discovered while filming a scene as Tonto for the upcoming Disney movie.
A video showing behind-the-scenes action from the film shows Depp and Armie Hammer, who plays the Lone Ranger, riding their horses, Silver and Scout, at a fast clip. Depp starts to slide out of the saddle and eventually tumbles completely off his horse, and is briefly run over by its hooves. A medic is called, and Depp displays what appear to be hoofprints on his tanned chest, though he's standing up and appears fine.
"The positive thing is, my coccyx (tailbone) didn’t take it," Depp jokes.
"This is a massive undertaking, it's really dangerous," director Gore Verbinski says of the film.
The movie has other frightening scenes, the video reveals. In one, Hammer stands atop a tall platform as a production helicopter swoops dangerously close, leading the actor to fear that he was about to be blown off.
"The audience is so sophisticated now (that) they can tell when it's CG (computer generated), they can tell when you're faking it," said producer Jerry Bruckheimer.
"It was the hardest movie I've ever made," Verbinski says of "The Lone Ranger." "But that's good because it feels like we're creating something completely new and exciting."
"The Lone Ranger" opens July 3.
