L'entreprenant Mr Petrov

... because there's not that much Fred and Ginger actually dancing together versus the other Astaire and Rogers films of the 1930s.

As for the plot, Fred Astaire plays Peter Peters, an American ballet dancer billed as "Petrov". Publicity has him billed as such so that he can cultivate the public persona of a demanding and temperamental Russian. He falls for fellow American singer/dancer Linda Keene (Rogers) and finds out she is sailing the next morning on the Queen Anne. He also books passage on the same ship at the same time, hoping to strike up an acquaintance with her on the voyage from Europe to New York. Both Peters and his manager Jeffrey Baird (Edward Everett Horton) tell a woman who is basically stalking Peters -to put it in modern terms - that Peters is secretly married to Linda Keene in order to get her off his case. Instead, this rumor begins to circulate in the press with Linda blaming Peter for telling the press this falsehood, and the resulting misunderstanding threatening any burgeoning relationship. Complications ensue that include a rather frightening looking mannequin in a comedic situation.

It was good to have Eric Blore and Edward Everett Horton back in larger doses in this film. Astaire always made a great comic foil for Horton and Blore and Horton always played off of each other exceedingly well.

Astaire and choreographer Hermes Pan try some new and novel numbers in this one. Included is "slap that bass" with Fred dancing and an African American band singing and playing in the engine room of a ship. Also, there is the dance duo with Astaire and Rogers doing a dance number on roller skates. Astaire liked to do his dance numbers in one take, without editing, but the complexity of this number required multiple takes, and Astaire realized that. The duo skated 80 miles before shooting was complete. Then there is the ballet number that is part of the big finale with ballet soloist Harriet Hoctor whose specialty was performing an elliptical backbend. It hurt just to watch her, and she is probably one of the few people on earth who could kick herself in the head.

If you like the other Astaire/Rogers collaborations you'll like this one. Sure, it's the same basic romantic formula, but the song and dance numbers always delight.
