warning: this all new movie contains never-before-seen content that is outrageous and highly inappropriate! BAD GRANDPA .5 gives you a whole new perspective on the world of irving zisman with unbelievable bonus scenes and hilarious pranks featuring catherine keener (as irving's wife "ellie") and spike jonze (as "gloria")... plus a look at the evolution of johnny knoxville's naughty alter-ego, the academy award nominated makeup effects, and an exclusive behind-the-scenes peek at the idiocy it takes to make a hidden camera movie in public. irving may be too old to chop the lettuce but he can still toss the salad!
