NOW THIS is what 3D was designed for. Forget alternative universes and recreations of prehistoric Babylon – the process has always been best suited to the firing of dangerous objects at blameless, ducking viewers.

You can probably see where this is going. Do the

Jackass

team propel such items from smellier parts of their lower anatomy? They certainly do. Indeed, in one notably surreal sequence, an unattached penis makes its way towards the camera and onwards to surprising aerial adventures. Then there’s the vomiting. You might wish to bring an anorak to the cinema.

For all that, the latest compilation of horrible stunts rapidly decays into just another Jackassfilm. The novelty of the 3D process wears off and the uninitiated begin to resent the repetitive accumulation of explosions, dunkings and compound fractures.

However, Jackassfans will find little to complain about. The combination of Dadaist mayhem and freak-show exhibitionism (Spike Jonze remains involved) seems increasingly like a turn-of- the-century thing, but the gang still unveil the odd jaw-droppingly larksome jape. I probably don't need to explain which body part stands in for a squirty volcano on a model-train layout.

Eugh! For enthusiasts.
