In my earlier post on comic books based on Broadway plays, I said others might write in with examples which hadn't occurred to me. So far, nine of you have written to remind me that in 1987, DC issued an adaptation of the then-forthcoming movie version of the musical, Little Shop of Horrors. That's not really an example because the stage version was (then) only an off-Broadway show. Little Shop didn't play on Broadway until a production in 2003.
Still, it's close…and I should have remembered it because I was (I believe) the first writer assigned to do the adaptation. Legendary DC editor Julius Schwartz called me up one day and offered me the job, I accepted and then, a day or three later, he called me back and apologized profusely. He'd jumped the gun, he said, and someone at the company was forcing him to use another writer. No, I was not angry. This kind of thing has happened so often that I've learned to expect it occasionally and to just shrug. It's healthier.
I also should have remembered that I did adapt a movie based on a Broadway musical for DC Comics. Dan Spiegle and I worked on an adaptation of The Wiz but it was halted in the midst of the drawing stage and never published. I wrote about it here.
And since we're mentioning the off-Broadway Little Shop, let's mention Starstruck. John M. Vohlidka wrote to remind me that Elaine Lee wrote and starred in that play and that artist Mike Kaluta did design work for it. It ran off-Broadway in 1980 and again in '83. Lee and Kaluta turned it into comic book format for Comix International and Heavy Metal and later for series and graphic novels at Marvel, Comico, Dark Horse Comics and other publishers.
Okay, what else did I miss?
