Johnny Knoxville's latest foray into "jackassing" America comes out Friday, October 25.
In Bad Grandpa, Knoxville plays 86-year-old Irving Zisman, who is taking his grandson Billy (Jackson Nicoll) on a road trip across the United States to live with his father after his mother is incarcerated. In true Jackass fashion, the movie is peppered with hidden camera pranks and stunts.
