In Garry Marshall’s Boxing Day, a bunch of American celebrities are put under a body-swapping curse on The Graham Norton Show after failing to drive on the left side of the street. They search for love and meaning across London, while stuck in the wrong bodies and also attempting British accents. Tom Hiddleston stars as Robert De Niro, Benedict Cumberbatch is an actual otter, and Ariana Grande is everyone else in the cast.
