Jackass Presents: Bad Grandpa will go head to head with the immensely popular and successful Gravity this weekend, with Johnny Knoxville and co. standing the best chance of ending the space spectacle's domination of the October box office. Gravity has held on to the top spot at the box office for the past three weeks, and other than Captain Phillips it hasn't really had any viable competition to knock it of it's perch. Bad Grandpa looks set to tip the balance of power in their favour though.

Bad Grandpa
The film has been given a mixed reception so far

The best way to describe Bad Grandpa would be as low brow comedy, performed and presented in a high brow manner. Fans of Jackass won't be disappointed at the sheer magnitude of gross-out pranks and hilarious stunts, and the Jackass boys have managed to once again create a movie that more of a modern-day Three Stooges than it is a compilation of idiots acting idiotically. But unlike any previous Jackass films, Bad Grandpa will follow some kind of plot - one based around the two central characters; octogenarian Irving Zisman (Knoxville) and his 8-year-old grandson Billy (Jackson Nicoll). Of course, there will still be plenty of idiotic behaviour taking place throughout the film.

The film follows the unlikely twosome across America, as Irving attempts to show his grandson what the US has to offer that his parents won't let him see. This involves heading to strip clubs, beauty pageants, weddings and funerals (uninvited) and causing havoc wherever they are. It's a tried and tested formula, and one that may just be popular enough to distract people from the pull of Gravity.

Jackass Presents: Bad Grandpa is out in cinemas now.
