A glowing paper chestnut brazier stands outside a shop window hung with gold garlands. A red hat lies in the gutter beside layered amber and blue puddles.

A paper chestnut cart glows beside a dark riverside, with curling steam, baskets of chestnuts and amber light reflected on wet paving.

The story

About Don't Open Till Christmas

In the days before Christmas, someone is murdering men dressed as Santa Claus across London, starting with a wealthy man stabbed in front of guests at a costume party. Scotland Yard's Inspector Harris and his sergeant, Powell, chase a killer who stays a step ahead, while the dead man's daughter, Kate, and her busking boyfriend, Cliff, are drawn into the case and fall under suspicion. A peep-show worker who witnesses one of the killings becomes the next target, and the trail leads back to a Christmas long ago.

The CineClaus verdict

A British slasher in which somebody spends the run-up to Christmas murdering every man in London who puts on a Santa suit. It is ramshackle and mean-spirited, and its troubled making shows in scenes that were plainly reshot with a different cast.

The kills are inventive, and it catches the grubbiness of early-80s Soho almost by accident. The season gives the killer his list and nothing more. One for slasher completists and bad-film nights, never the family sofa.
