This time of year it may seem that every holiday tradition from around the world has been commodified in the United States, but one that hasn’t caught on is the British panto, a comic family entertainment widely produced throughout the U.K. at Christmastime. Happenstance Theater, the Washington, D.C.–based troupe behind Adrift, doesn’t name panto as one of the many influences on its quirky and clever show, but there are similarities: a vaudevillian essence, British accents, physical comedy, musical interludes, commedia dell’arte–type characters, audience participation, elaborate costumes, a touch of the ribald.
