Just when you thought the world was free of slapstick comedy and hidden camera pranks from a group of testosterone-fuelled lads - think again.

Later this year will see the return - and final, final (final?) outing - for Johnny Knoxville and his band of mayhem makers. 'Jackass Forever' is arriving on our cinema screens this autumn.

Judging from the trailer below, the group of pain-lovers are older than the last time we saw them, but they're still as wise as ever. Read: they're not very wise at all.

Johnny Knoxville - who was 49-years-old during filming - will once again be joined by his right-hand men. Steve-O, Chris Pontius, Dave England, Wee Man, Danger Ehren and Preston Lacy will be back - all of whom have either appeared as part of the three previous movies or were part of the original MTV TV series.

There will also be some new fresh meat joining the team, with 'Jackass Forever' introducing Jasper, Rachel Wolfson, Zach Holmes, Eric Manaka, and some guy named Sean "Poopies" McInerney. Lovely.

The past 11 years has been 'Jackass'-free, with 'Jackass 3D' (remember 3D?) releasing in 2010. With pretty small budgets in the low millions, the 'Jackass' movies have been incredibly popular with moviegoers in the past, and we have to admit we're looking forward to seeing what elaborate opening the 'Jackass' gang have opted for this time around.

Production on this final film of the franchise began in December last year, as was directed by Jeff Tremaine, who helmed all of the previous movies including the spin-off 'Jackass Presents: Bad Grandpa'.

Promising plenty more pranks, and a hell of a lot more pain, here's the trailer for the fourth entry in the 'Jackass' movie franchise.

'Jackass Forever' will open in theatres on October 22.
