He spits out lame dialog like it was Shakespeare, he talk-sings with a verve that could give Rex Harrison or Robert Preston lessons, he stomps up and down, he uppercuts, he dances up a storm. There's plenty of A-list talent in this uninspired Warners musical, but a 51-year-old Cagney is pretty much the whole show, and he appears to believe in the hole-filled plot so much that you buy it, too, despite the many lapses of logic. I find his teaming with Virginia Mayo a little distasteful--he's plainly too old for her--but she lends a lot of enthusiasm, too, as does Doris Day, given some middling Jule Styne-Sammy Cahn ballads to warble (and some very unattractive gowns to model), and Gene Nelson, tapping exuberantly, and Gordon MacRae, with his fine natural baritone. Cagney felt he did his best dancing in this film, and it's worth sitting through the dated, hit-you-on-the-head patriotism and weird plot mechanics to get to his virtuosic numbers--he even taps a bit with Day, who started out as a dancer and keeps up brilliantly with him. It's not a good movie, exactly, but I'd trade a lot of neater, better-crafted musicals for this one's dumb liveliness, and for Cagney's genius. I mentioned Robert Preston above; Cagney was, in fact, considered for Professor Harold Hill before Preston was hired. I think he'd have been terrific.
