You always know it's the witching season when squads of zombie and vampire flicks lurch into town to take bites out of your wallet. Creeping on the heels of Zombieland and Pontypool, this week's avatar of the former genre is Colin, a low-budget feature whose principal claim to fame is its budget, officially £45 (that would just about buy you eight copies of the DVD, which goes on sale on Monday). The question remains, though, whether the result is a treat or a trick, an instant lo-fi classic or a tacky gimmick that turns into a pumpkin at midnight.

About three minutes in, Zombieland is shaping up to be quite the spewiest film in the history of Technicolor. While the lopped-limb count is also off the chart, the litrage-to-frame ratio of mewl and puke, of gump and vom and spurting, gushing intestinal bile sets new parameters for an opening sequence. We begin, in short, in medias res. Has any movie ever so totally shot its wad before you've even dipped a fist in your popcorn? (Apart from Saving Private Ryan, obviously.)
