Johnny Knoxville has revealed he already has some ideas for a fourth Jackass movie.
The 41-year-old practical joker reckons there could be enough scope for another big-screen adventure of the stunts show in the future.
"Well, we said we weren't going to do a two or a three, and there's probably more of a chance of a fourth film. We're not planning anything right now, but I always write for it," he said.
Johnny also revealed that he is working on a spin-off to the MTV reality TV series.
"There's another thing we have in the works - an off-shoot of Jackass that we are working on. I can tell you more on that later but there are a lot of things coming down the pipe," he added.
The actor - who tends to do his own stunts on Jackass - had to get used to seeing stunt doubles in The Last Stand, which he stars in alongside Arnold Schwarzenegger.
"I do as much as they let me. It's so weird - on Jackass, I do everything, but it changes when you get onto a regular movie. I had worked with the stunt co-ordinator before, so they always let me do as much as possible, before the insurance people step in," he said.
He added: "I wanted to do everything. Eventually if they think you're going to get killed or broke off (injured), then they will stop it but I always like to do as much as possible."
:: The Last Stand is in cinemas now.
