Actually Gaby Duval was the name of the actress in the movie. Her actual name was Zizi Jeanmarie. She was the only bad part of the film. Why she was picked for Bing's leading lady I will never know. Phil Harris was in the movie too as Mitzi Gaynor's dad. I wish he and Bing would of had a duet together...all in all a good film.
You are absolutely right - I transposed the movie name - Regarding casting - I wish Mitzi had been Bing's Leading Lady - Yeah, I like the movie too - You can tell Bing and Phil are good friends for real when Phil says (in character,to Bing) I knew you were a regular guy - and Bing smiles or laughs a knowing look -
