Christmas in the U.K means mince pies, mistletoe, a glass of wine or two—and a movie run. Prince Charles Theater in Leicester Square, known for its cult art house and classic movie screenings, is the place to go. Its aged interiors are cozy and charming. This year, the programming includes the classics The Muppet Christmas Carol, Home Alone, and Elf. Grinches can saunter into another screening room and catch Goodfellas and The French Connection. —Elena Clavarino
