It was Turnabout, back in 1931, that set the tone for all the subsequent body-switching (or whatever) stories to come. Smith’s original story was made into a movie in 1940, then a short-lived TV series (1979) starring John Schuck as Sharon Gless, or something like that. (For the moment, we won’t mention a certain episode of Star Trek.)
Of course, nothing says you can’t swap individuals of the same gender; in fact, it’s actually an older premise, dating to F. Anstey’s 1882 Vice Versa, which interchanges father and son. (Mother and daughter, you’ll remember, were swapped out in Freaky Friday.) Best buds were transposed this year in The Change-Up.
Which brings us to the case of two women who aren’t exactly friends, in Kevin Bleau’s musical If You Want My Body:
[It] tells the story of Mildred, a rich but overweight lawyer who yearns for her first relationship. Annelies, a slim dancer, is about to be evicted from her studio. The women make a deal with witch Lorana to swap their brains into each other’s bodies. Annelies’s brain will lose 50 pounds from Mildred’s body. Then Lorana will return the brains to the original bodies and Mildred will pay both women. The women question their philosophies on life as they “walk a mile in each other’s bodies.”
Act II is playing tonight in Boston, with David Reiffel directing, which is why I’m bringing it up now.
