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 chic, brownies and popcorn also lies within. Only one way to find out right? Based on the famous Dr Seuss story, Jim Carrey plays the nasty, green monster with a foul attitude living in exile from Whoville. Banished to a grumpy seclusion, the Grinch hates Christmas (for shame!) & plots to steal it from the Whos in any cunning way he can. That is, until Cindy Lou Who spreads her childish charm. Watch this screening of The Grinch & let all your holiday hatreds melt away. Certificate: PG. Runtime: 1 hour 40 minutes. Doors open at 4:00pm, film starts at 5:00pm. Seating is unallocated, but the screen is on a stage so it's hard to get a bad view.
