A Director said: "I mean no disrespect to Miss Reynolds, whom I always loved. But it's not as if she's going to appear in a revival.
Oh, dear! Gavestonas I would love to see Singin' in the Rain with Drag Queens and Kings playing all the roles. I read Brecht was going to produce such a production, but he died before it could happen!
"
To my ear, that sounds like something Brecht would say (like his famous assertion that Ethel Merman would make the ideal Mother Courage) rather than actually do. But it certainly sounds like fun. (To be fair, Brecht was making a point in saying Merman should play Courage; I just don't think it is something he would have ever done. Certainly not after meeting Merman.)
I just don't think the unfortunate death of Debbie Reynolds would make enough box office difference to insure a successful Broadway run. A revival might succeed, of course, but it won't be because anyone died.
