So many stage musicals have been ruined by their film versions. I agree with almost every one that's been posted here: BYE BYE BIRDIE, MAME, FORUM, A CHORUS LINE, ANNIE.
I'll add GUYS AND DOLLS which does have the Michael Kidd choreography and Vivian Blaine, but while Jean Simmons is tolerable, I'd throw out both Brando and Sinatra, reinstate the cut songs and get rid of the new ones.
