The movie has three other dance numbers, two solos by Astaire that are wonderful but not transcendent, and a final duet with Rogers ("The Piccolino"), where one of Irving Berlin's lesser songs is redeemed by the sight of Astaire and Rogers dancing all over a huge set that is intended to represent a canal-side hotel in Venice and looks every bit as realistic as the Grand Canal Shoppes at the Venetian in Las Vegas.
The movie's plot depends on a misunderstanding that is all but impossible: Ginger falls in love with Fred, then mistakenly decides he is the cheating husband of her best friend, Madge. "How is it that Ginger has never met her best friend's husband?" Alan Vanneman reasonably asks in the Bright Lights Film journal. "Well, Europe is a big place."
Yes, and Madge and her husband, Horace, spend long periods living separate lives of luxury. That Horace is a womanizer seems, strangely, to cheer Madge, perhaps because none of the sex in this movie seems to require body parts. That's why she gives her blessing to what Ginger thinks is adultery. She even pushes the couple onto the dance floor for the "Cheek to Cheek" number.
This is an Idiot Plot, yes, which could be cleared up at any moment by one line of sensible dialogue, but there are times when nothing but an Idiot Plot will do, and we are happy to play along. The movie, made during the Depression in 1935, features characters so rich that even their butlers are gentlemen of leisure. Astaire plays Jerry Travers, who is opening in a London musical being produced by his best friend, Horace Hardwick (Edward Everett Horton), which means he doesn't know his best friend's wife, either.
For reasons utterly contrived, Jerry is staying in Horace's hotel suite, which is why Dale Tremont (Rogers) finds Astaire when she rings Horace's doorbell. As the film opens, Horace advises Jerry on the pleasures of marriage, and Astaire insists on the joys of bachelorhood with "No Strings," a Berlin song with lyrics that could have been written by the naughty Cole Porter:
His tap dancing during this number disturbs Dale, who is sleeping directly below them in a bedroom that looks like where Botticelli's Venus spends her nights when the clamshell gets damp. She comes upstairs to complain, he falls in love, and the next day buys out the hotel flower shop to fill her room. "I wonder what Mr. Beddini is going to say about this," the shop owner muses to an unbilled Lucille Ball. "The desk clerk has intimated that Mr. Beddini provides Miss Tremont with all the niceties, including her clothes. And her niceties are very nice."
Alberto Beddini, who often speaks of himself in the third person, is played by Erik Rhodes as a dress designer who pays Dale's expenses in return for her showing off his gowns at fancy watering holes. That he is gay goes without saying, and in 1935, it did. At one point, fed up with Dale, he declares, "Never again will I allow women to wear my dresses."
Jerry and Dale meet in the hotel lobby, where she's on her way to riding lessons. He pursues her to the park, where her ride is interrupted by a sudden shower. She takes refuge in a pavilion where he finds her, and as the rain pours all around them, he sings "Isn't This a Lovely Day?" She tries to remain aloof, but when he begins to dance she begins, reluctantly at first, to join him.
When discussions come up about which of the two was the better dancer, people often quote a line that became famous after a 1982 Frank and Ernest comic strip: "Ginger Rogers did everything Fred did, and she did it backwards and in high heels." Although she is wearing riding boots and not heels in this scene, what is remarkable is how supremely the two dancers work together. The dance begins as a solo by Astaire and then becomes a conversation in dance, each one performing a dazzling step that the other reproduces, until they are in perfect synchronicity. After watching this scene, there is only one thing to be done, and that is to watch it again.
Dale is now in love with this man, whoever he is. Then a hotel clerk points out "Mr. Hardwick" on the mezzanine, she thinks he's pointing to Jerry, and is furious to have been romanced by a married man. She confesses all to Madge (played by Helen Broderick, who was the mother of Broderick Crawford, and we can believe it). But Madge is elated by the news, the latest in a series of dalliances by Horace that result in payoffs of diamonds and furs for her. Horace, who doesn't know about the mistaken identity, thinks Jerry and Dale are simply having an affair, and assigns his butler, Bates (Eric Blore, an ingratiating busybody), to shadow them and keep Jerry out of trouble before his show's big opening night. Astaire arrives late at the theater, just in time for his "Top Hat, White Tie and Tails" dance number, which provided his signature song.
