Johnny Knoxville has gone back on his word never to make another Jackass movie, revealing how "excitable" he has become about a sequel. The daredevil actor, who co-created and starred in the stunt-filled TV series of the same name, decided to quit after the first movie hit top spot in the US film chart - until his influential co-stars came up with even more crazy ideas. He says, "I meant it (when I said Jackass was done). At the time I felt that way, but I was travelling with the WILDBOYZ cast (TV stunt show), and I went to Indonesia and Argentina with them, and started getting rather excitable, up for anything. "Then me, Spike Jonze and Jeff Tremaine the director started talking and the next thing I know I'm apologising for saying we'll never do Jackass again. F**k!"
