Jackass Presents: Bad Grandpa .5

Jackass Presents: Bad Grandpa .5 is a comedy built from unused material shot for the earlier hidden-camera film about Irving Zisman, an elderly man travelling across the United States with his young grandson, Billy. This follow-up mixes those extra scenes with new pranks and behind-the-scenes footage, and it brings in additional performers who appear alongside Johnny Knoxville's character.

Jeff Tremaine directed the film, which sits between Jackass Presents: Bad Grandpa and The Dirt in his filmography. He wrote and produced it with Spike Jonze and Johnny Knoxville. Knoxville again plays Irving Zisman, and Jackson Nicoll returns as Billy. Spike Jonze appears as Gloria and Catherine Keener as Ellie, with Georgina Cates and Zia Harris also in the cast. The 86-minute production was made by MTV Films and Dickhouse Productions.

On TMDB the film holds a rating of 6 out of 10 from 288 votes, placing it in moderate territory with a relatively small number of viewers weighing in. It belongs to the Jackass series of films and specials, which Tremaine has directed across more than two decades, and it is positioned as a companion piece to the 2013 feature rather than a standalone story.
