It's usually the case that hit plays get turned into movies. But more and more nowadays, the opposite is happening, with films being translated for the stage. Some say it's a sign of intellectual bankruptcy in theatre. Hollywood has the same problem, but there are a lot more new successful movies in the last two decades than new successful plays. So the stealing ends up being one way. This trope can be taken one step further, by going from movie, to stage musical, to Recursive Adaptation movie-of-the-stage-musical.
