Flannery O’Connor sold one of her stories for production on TV. A couple of mentions of this in her letters:

I have just learned via one of those gossip columns that the story I sold for a TV play is going to be put on in the spring and that a tap-dancer by the name of Gene Kelly is going to make his tellyvision debut in it. The punishment always fits the crime. They must be going to make a musical out of it. This is the story about Mr. Shiftlet who marries the old woman’s idiot daughter.

And then, later,

I am writing my agent to make haste and sell all my stories for musical comedies. There ought to be enough tap dancers around to take care of them, and there’s always Elvis Presley. Momenti mori.
