Knoxville’s performance is outstanding, as he never fails to please his fans and viewers of his movies.

Unlike the other previous “Jackass” movies, “Bad Grandpa” contains fewer daring pranks. Instead, the pranks are played by Knoxville as he pulls ridiculous pranks on people, with hidden cameras here and there capturing everything. Knoxville did a great job of keeping his audience laughing from the start of the movie until the end.

His character as an old grandpa was phenomenal. The way he walks, talks and styles himself resembled grandpas we see today, not to mention his make over. Viewers will see that Knoxville has embraced the grandpa character within himself by the way he performs in the film. It was as if he believed at some time that he became who he was acting as, a grandpa. His acting is spot on and perfect, as the pranks were unscripted and take place with real people with their real reactions. 

Knoxville is brave enough to perform outrageous pranks and be the actor he is. In the film, you will see that his acting is so natural and you will learn that all he wants to do is have fun pranking people. It may lead you to think that no matter how old or young you are, you can still have fun and be the person you really are.
