The odds for a white Christmas in London have dramatically increased thanks to Pop Up Screens. Head to Notting Hill's 20th Century Theatre and step through their magic wardrobe to discover a secret cinema surrounded by snow. Rumour has it that a bar filled with an abundance of mulled wine, hot chocolate, brownies and popcorn also lies within. Only one way to find out right? Macaulay Culkin might currently be in a pizza-themed Velvet Underground tribute band (true fact), but it all started when he was but a lad. Home Alone is a quintessential Christmas classic. Poor Kevin gets left behind when his parents go on holiday and defends himself in the most hair-brained and slapstick ways possible against two would-be thieves. Certificate: PG. Runtime: 1 hour 43 minutes. Doors open at 7:30pm. Film starts at 8:30pm. Seating is unallocated, but the screen is on a stage so it's hard to get a bad view.
