Marge and Gower Champion are great in this film.

"I Won't Dance" and "Smoke Gets in Your Eyes" are on youtube. See for yourself:

Great talent, good looks, and chemistry; Marge and Gower had it all.

But Gower wasn't a tap dancer, and that's perhaps the reason the Champions refused studio offers to remake more Astaire-Rogers musicals in color.
