Johnny Knoxville suffered brain haemorrhage after brutal Jackass Forever stunt: “It was a tough one to come back from”

Johnny Knoxville has shared how he's "done enough" large and extreme stunts now after suffering from a brain haemorrhage while filming the upcoming Jackass Forever movie.

In a new interview on The Howard Stern Show, the Jackass star explained that he broke his wrist and ribs, and suffered brain damage, after getting charged at by a bull (a brutal image of the moment it happened was one of the first teasers for the film last year).

"The bull hit was the worst hit I’ve ever taken from a bull or maybe period," Johnny said. "I remember taking some tests. The neurosurgeon said, ‘Do you have trouble paying attention right now?’ I said, ‘Yeah, why?’ He goes, ‘Because you scored a 17 on [your attention].’ That’s out of 100.

“I had to go under all these type of treatments, this transcranial magnetic stimulation, which they buzz your head with these magnets for about 30 minutes at a time for like, oh God, I would say 10 to 12 treatments over a series of two months and it’s supposed to help with depression and help with my cognitive skills. It was a tough one to come back from. I was trying to edit the movie at the time but I couldn’t sit still.”

Miraculously, he revealed that he's now "the healthiest I’ve ever been" after taking medication and doing therapy, and has since decided that he'll retire from the more reckless stunts, not wanting to risk any more blows to the head in particular.

"I don't have anything to prove," Johnny stated, "and I still have control of all my faculties, so I don't need to do large stunts anymore."
