Not to be confused with the similarly titled Robert De Niro vehicle 'Dirty Grandpa', this earlier comedy starring Johnny Knoxville could be dubbed "Dirtier Grandpa" with gags that are cruder and push barriers even further. The plot revolves around an old man reluctantly taking his grandson on a road trip to meet his estranged father, gradually bonding with him along the way. Simplistic as this may sound, it is admirable that the filmmakers were actually able to create a cohesive narrative here given that the film involves unsuspecting individuals being pranked by the film crew a la 'Borat' and 'Brüno'. Not only that, they are often pranked in quite dangerous ways, with Knoxville forced through a glass window at one point! For a film involving grandfather and grandson though, the film derives a few too many laughs from just the old man for its own good. It is quite telling that the film's absolute best scene involves a child beauty pageant that they crash late in the piece, with the fact that they are both 'in on it' together rendering it such a memorable sequence of events. Knoxville is, however, skilled enough to carry the film in his moments without his youthful co-star, and Oscar nominated makeup or not, his portrayal of a man more than twice his actual age is nothing short of remarkable. This is also one of those rare movies that is worth sitting through the whole end credits for; not only do we get to see Knoxville pre and post makeup, we also get to see the reactions of those pranked after finding out that they are in a candid camera type film.

I never really got into Jackass films, so this was the first one that i truly watched. I have to say it was funny and worth watching but its so dumb at times that i couldn't help but hope some scenes would end faster ("Strip Club" and "Post Office"). The lead character grandpa -Johnny Knoxville- who i really liked in 'The Ringer' goes on a road trip to bring his grandson, Billy, to his dad, Chuck, who is a slow witted, poor, druggie that doesn't care about his son. The reason that he has to take care of the kid is because the mother got arrested for violating parole. The movie starts off with a bang when grandpa gets something stuck in the vending machine and begs onlookers to help. This movie was basically a series of pranks on unsuspecting people. Supposedly it was real and not fake but there were times when i felt the reactions of the people were not serious enough to be real. In between the pranks a story is woven between a grandfather and his grandson bonding. Of course, grandpa doesn't much care for the boy's company when he is going after women. Jackson Nicoll, who played Billy did a great job, he had great chemistry with Knoxville throughout the film. 7/10 I thought it was a little overrated because of how truly dumb it is but at it's core the 2 main characters are memorable and likable and there are some serious laughs in this movie.

Not much time to say a lot..so I will just say THANK YOU!!! It was brilliant and so hilarious...we laughed our as....s off here! I also liked that there was a good show of humanity and compassion such as in the biker bar scene. I think it takes a lot of courage to be outrageous, to say and do the things the actors did, to unbeknownst people all through the taping of this movie. To put oneself at risk of being beaten up or worse is amazing to say the least. The young lad is certainly a real trooper and future success for more work in the industry! I tip my hat to you all involved and will look forward to many more belly-busting and improvising works of real true comedy in it's most basic form...the unsuspecting receivers! Keep it up and make more stuff! I, we love it!

I've never been a Jackass fan , but "Bad Grandpa" was genuinely hilarious. There's a narrative to the movie, but really that's just an excuse for the antics. And Knoxville is on fire here. The man deserves hug credit for never cracking up in the middle of a prank, and that takes serious skill. The vending machine, the male strip club, the "shart" scene in the restaurant - they're constantly going to unbelievable lengths, and half the fun is just seeing the peoples' reactions. I had a lot of fun with this movie, a pleasant surprise indeed.I don't know where they could take this story-wise, but count me in for a sequel.7/10
