Bad Grandpa .5 gives you a whole new perspective on the world of Irving Zisman with bonus scenes and pranks also featuring Spike Jonze as "Gloria" and Catherine Keener as Irving's wife "Ellie", plus a look at the evolution of Johnny Knoxville's naughty alter-ego, the makeup effects, and a behind-the-scenes peek at the idiocy it takes to make a hidden camera movie in public.
Unfortunately the movie Jackass Presents: Bad Grandpa .5 is not yet available on HBO Max.
