Bruce Dern wanted to make a cameo in Jackass Forever
Sadly, by the time the Jackass crew got his request, the movie had wrapped filming

There’s a reason why after two decades and now that they’re into middle age, the Jackass guys are still at it. They make stunts like getting kicked in the nuts, bitten by snakes, and being knocked out by a pro boxer look extremely fun, because it is—for them, at least. So, it’s not surprising that anyone outside of the Jackass inner circle would want to join them. And, there is one surprising Oscar-winning actor who wanted to participate in the debauchery for Jackass Forever.
During a recent appearance on The Howard Stern Show, Johnny Knoxville says that though they usually feature celebrity cameos from people they have a working relationship with, like Eric André (who’ll appear in Jackass Forever), there was someone who actually reached out asking to make a cameo: Bruce Dern. However, by the time the Jackass crew heard about it, it was too late.
