Well, now you've got me curious. Let's take a look. It looks like the actor who danced with Vera Ellen in White Christmas was none other than Bing Crosby. It's no surprise, since Bing Crosby was a big star in the 1940s and 50s, and he had a great singing voice and charisma on screen. He was perfect for the role of Bob Wallace in White Christmas, and his chemistry with Vera Ellen was undeniable.
