Bad Grandpa

Le vieux Irving Zisman, quatre-vingt-six ans, parcourt les États-Unis avec un improbable compagnon : son petit-fils de huit ans, Billy.

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.
