I thought the casting of the movie was fine, and as a film it was "good enough" for the general movie audiences of the day. And don't forget Charles Durning even got an Academy Award nomination for his show-stopping, "side-stepping" turn as the governor.
I did the show several years later with Becky Ann Baker (formerly Becky Gelke of the original cast), and it was then that I realized how much heart they had cut out of the film. Particularly when it came to the "girls." They were not just chorus/atmosphere as they are in the film. Two of them (Angel and Shy) were nicely fleshed out (as far as supporting characters go), and the others all had "identities" as people, not just as a generic group of eye candy.
By reducing the whores in that whorehouse to "furniture" they took away our care and our chance to empathize with any of them. And that was the real shame.
So we got The Dolly & Burt show, instead. Not bad... but not "Whorehouse" either.
