Johnny Knoxville claims a "monstrous explosion" on the set of Jackass 5 was mistaken for a plane crash.

The 54-year-old star - who co-created the iconic MTV stunt show franchise, which launched in 2000 - will be back with Steve-O and the gang for a fifth film which is due for release on June 26 and he's now revealed one of the stunt worried residents in Simi Valley, California.

In a post on Instagram, he wrote: "Apparently people thought a plane had crashed yesterday in Simi Valley. Little did they know it was from a monstrous explosion @jemfxpopov [Special Effects Supervisor Elia Popov]created for us for the final day ever of @jackass filming."

He went on to add: "We were standing near the explosion and couldn't believe what we were seeing. Immediately after the entire cast went and hugged @jemfxpopov's neck.

"Thank you to Elia, his crew and the rest of our amazing crew yesterday to make sure we went out with a bang. 26 years and that's a wrap!! Coming to theater June 26th, Jackass: Best and Last."

It comes after Johnny insisted Jackass: Best and Last is the "natural place to end" for the franchise.

He told Rolling Stone magazine: "This will be the last one. "This is the natural place to end. So it's going to be absolutely awful."

The crew were last seen together in 2022's Jackass Forever, and Johnny insisted the idea of making a fifth film was "never" wise.

He quipped: "Well, it never was a good idea! It was just fun. You know how you have ideas that are terrible but are fun? This would be that."

When it comes to what fans should be hoping for this time round, the actor and stunt performer insisted the best case is a "train wreck".

He added: "You hope it doesn't go well at all! Should be a f****** train wreck. That's what you should hope for. I think we designed it that way."

The new movie won't feature original castmember Bam Margera, who previously declared no amount of money could convince him to return to Jackass. The TV star, 45, shot to fame as a member of the stunt show's cast back in the 2000s appearing in the small screen series as well as a number of films, but Bam struggled with substance abuse issues and he was cut from 2022 movie Jackass Forever.

Bam previously insisted he will never forgive his former castmates. He told CinemaBlend: "They have like new dudes, and what they did to me, making me go to treatment and paying for it, and then not putting me in a movie, and, you know, I had to go to court over it and I just, you couldn't offer me enough money to want to do another Jackass with them. The damage has been done."

Bam alleged he was wrongfully fired from the movie and he went on to to sue Paramount as well as his co-star Johnny and director Spike Jonze. The court case was settled in 2022.
