Who's that? This guy dancing with Vera-Ellen:
Here's my theory: John Brascia's role in this movie makes no sense at all. Danny Kaye is Vera-Ellen's love interest in the movie. He should be, by the usual logic of Hollywood storytelling, her duet partner in all her big dances. Indeed, Kaye and Vera-Ellen have a lovely dance early in the movie:
After that, though, it's Brascia — who utters no lines in the movie — who is the main dance partner. It's aided by the show-within-a-show conceit of the movie: They're practicing for an upcoming musical, you see. But again, this doesn't make a whole lotta sense...
...unless you consider this possibility: Brascia, and not Kaye, was the only dancer on set who could keep up with Vera-Ellen.
Yes, Kaye was enormously gifted as a dancer. But he was already in his early 40s when "White Christmas" was made. Brascia is a good 21 years younger. And Vera-Ellen is a hell of a dancer.
Watch this. Watch Brascia's feet, especially.
Love me some Danny Kaye. But he's not keeping up with Vera-Ellen there. John Brascia is.
It's OK! That's not a knock on Kaye. Vera-Ellen's vocals were dubbed by Rosemary Clooney. This movie knew what it's performers strengths and weaknesses were and adjusted accordingly. More than 60 years later, it's still a hell of a watch. And John Brascia, whose name I bet you didn't know, is one big reason why.
