This was, without doubt, one of Julie Andrews best films, but when it comes to Ms. Andrews, most of her films were beauts. I saw it in the theater sometime in the mid-60's and later got a DVD to add to my collection. I do need to brush up on my homework since I do not recall Carol Channing being in the movie or what part she essayed. What I recall are great songs and dances of the Charleston era, the 1920's. And, yes, the very handsome John Gavin being the leading man. I'll watch my DVD copy at home on Sunday. I have a faint idea that this was a Ross Hunter production; may be he also made Flower Drum Song, all Universal International productions.
I found it Saturday at a second-hand store. It is also up at the Internet Archive, but be careful downloading it as you may run afoul of copyright laws. That will not happen if you stream it there. Trouble is, fun as this movie is, its portrayal of Asian characters (two Chinese men played by Japanese actors and their "dragon lady" boss by a Canadian) is going to make this hard to swallow for the PC crowd. This play was often done by dinner theaters and repertory companies, but was shelved for now while they retool it for modern audiences. Think of it though - made in 1967 and set in 1922. Does 1979 seem that far away to us?
The only place I know of is Amazon, you have to buy the actual DVD. I imagine there are other places online to purchase it as well though. But it's not on any streaming services.
Popular Prices after the Roadshow where it played in just a few theaters at crazy inflated prices that's how they did it in those days, the 60s had many Roadshow pictures the studios thought they could make big money fast by releasing them that way.
First, they are different performers. Second, I much prefer the Broadway show and by extension, Sutton Foster, who is/was brilliant. Third, Sutton is not only NOT forgotten, she is bigger than ever! Try to stay in touch with reality occasionally.
