Rating: 2/5

THREE years after Harold and Kumar escaped Guantanamo Bay, the stoner buddies deck the halls with illegal substances in a loud, brash and outlandish escapade featuring potty-mouthed outbursts and gross-out moments wrapped in festive cheer.

The pair are reunited in the search for a fir tree to replace one they’ve set alight with a discarded marijuana joint.

This hit-and-miss comedy would surely have stumbled straight on to DVD were it not for the pointless use of 3D. The only time the eye-popping format impresses is during a deranged and imaginative claymation sequence, induced by a batch of drugged eggnog.

Belly laughs are tempered by sharp winces of pain, including Harold getting an appendage stuck to an icy metal pole and Kumar opting to warm up the painful situation with hot coffee.
