The 2004 cult comedy Harold & Kumar Go To White Castle saw our THC soaked titular heroes struggling to find a near mystical burger joint while avoiding a roving gang of extreme sports fanatics, having their car stolen by an ecstasy and coke-addled Neil Patrick Harris (of TV's Doogie Howser MD and How I Met Your Mother) and, in a moment of drug fuelled surrealism, riding on the back of a galloping cheetah.

This sequel picks up where the original film left off, with the intrepid pair of tokers bound for Amsterdam in order to track down Harold's (John Cho) object of desire, Maria (Paula Garces). Kumar (Kal Penn) is the instigator of the voyage, and as a precautionary measure, he smuggles his "smokeless bong" on board the flight. Several "bong/bomb" terrorist gags later, and the pair is in the custody of psychotic homeland security official Ron Fox (Rob Corddry). They're swiftly sent to Guantanamo Bay, where they must devise an escape plan and attempt to clear their names. Cue gratuitous gross-out humour, incest jokes, full frontal nudity and racism gags.

For audience members expecting a shrewdly constructed satire on Guantanamo Bay, look elsewhere. That said, it's still pretty funny, and although many of the gags are retreads of those from the previous film, we're still provided with many amusing moments, notably from Neil Patrick Harris, who takes the lion's share of the laughs, playing himself as a whore-mongering, mushroom-chomping freak with a penchant for branding women's nether regions with his initials. Just make sure that you're really stoned when you see it.
