Johnny Knoxville and his troupe, under the guidance of Jeff Tremaine, continues the gross-out, scatological extravaganza, this time using the Z-axis. Though much of the violent, incessantly crude sketch humor really doesn't really have the zany cohesion like the chaotic crew's last foray, Jackass: Number Two. Even if some inventiveness shows before a case of tedium sets in without the sublime inspiration of auteurs like Luis Bunuel or David Cronenberg.
Jackass 3D gets an intro from old and soon-to-be rekindled MTV kin Beavis and Butt-Head before letting plenty of gratuitous gags hit or miss in the protruding, if underwhelming dimension with a gag-reel to boot. It does use the format in a way to augment the canvas of concepts first realized as one of the cutting-edge reality shows a little over a decade ago.
Some of the outrageous stunts include pin a tail on a real donkey and some beehive tetherball offer some initial potential while the personal humiliation reaches high (or low) moments with the "High-Five" and "The Poo-Poo Supreme" (the latter having two cranes helping to make an outhouse stunt visually ripe).
Bam Margera and Steve-O have had their own off-screen issues, relational and rehab, respectively, as they (along with other fearless chums) help Knoxville (remembered for some big-screen work during this profitable series like The Dukes of Hazzard and The Ringer) put themselves through addled, visceral moments. Maybe, though, not with the same glee or heart previously displayed as "the making of" indicates some mellowing out around early middle-age.
Still, many of the Jersey Shore ilk will spring with laugh-out-loud delight when anatomical parts do their thing, even with some slow-motion 3D around new painful situations. Clearly around the closing credits the unlimited dangerous lunacy will finally wrap up, but not without some projectile motion and one droll candid camera bar fight involving Jason "Wee-Man" Acuna and the like(wee)se police.
