Jackass 4: Johnny Knoxville and Steve-O in hospital after just two days of filming

Pair were reportedly jumping on a full-speed running machine while holding large musical instruments

Johnny Knoxville and Steve-O have been sent to hospital after just two days of filming Jackass 4.

The actors and stunt performers, known for their work on previous Jackass films, were reportedly jumping on a full speed treadmill while carrying “band equipment”, including a tuba, when they sustained injuries. 

Screen Rant report that neither star is seriously injured, and filming on the forthcoming sequel, the first entry in the series since 2010’s Jackass 3D, is expected to resume soon.

Jackass star Bam Margera posted about the incident, saying in a video: “It's the second day of filming Jackass already and Steve-O and Knoxville were hospitalised by jumping on a full-speed treadmill with band equipment - like a f***ing tuba.”

“So yeah, I'm here are the clinic now, taking a p*** test. Rock'n'roll, oh yeah - I've got the scars too. Yeah man.”

The fourth Jackass film was originally due to be released in cinemas next March, but has been pushed back until 2 July 2021 because of the ongoing coronavirus pandemic.

Jackass 4 will be the first film involving the whole Jackass cast to be made since the death of cast member Ryan Dunn in 2011, at the age of 34.

Earlier this year, Jackass 3D star Stevie Lee also died “unexpectedly” at the age of 54.
