Alexia Khadime (R) prepares for her role as Princess Tahlia, ahead of a performance of the traditional pantomime "Sleeping Beauty" at the Hackney Empire on December 13, 2016 in Hackney, England. The show runs from November 26, 2016 to January 8, 2017, with many days having two performances. A pantomime is a musical comedy stage show, traditionally performed around the Christmas period for families, with many moments of audience interaction and regular characters appearing, no matter the story. These can include a gender reversal where "The Dame", a major female character, is played by a man, and the part of lead "boy" is filled by a young actress.  (Photo by Leon Neal/Getty Images)
