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? For this screening, join Anna on a journey to find her sister Elsa, whose icy powers have trapped the kingdom of Arendelle in an everlasting winter. With an unforgettable roster of songs throughout, including the unforgettable Let It Go, this is pure fun for all of the family. You'd have to have a heart of ice to not enjoy this modern Disney classic.
