Bing Crosby, Vera-Ellen, Rosemary Clooney and Danny Kaye in "White Christmas."

If you've never seen the 1954 holiday classic "White Christmas," you really won't have an excuse any longer: AMC will be airing the movie seven times in a row, starting at 7 a.m. on Christmas Eve.

In case you've been buried under a snowdrift, for, oh, half a century or so, the movie features Irving Berlin's music and concerns two former Army buddies (Bing Crosby and Danny Kaye) who put on a show with a sister act (Rosemary Clooney and Vera-Ellen) to save their general's Vermont hotel.

Here are five things you may not have known about "White Christmas."

The studio's original plan was to reunite Fred Astaire and Crosby, who co-starred in "Holiday Inn" (1942), the movie in which Der Bingle sang "White Christmas" for the first time. But Astaire refused, so the part was redone for Donald O'Connor, who later pulled out, with Danny Kaye finally stepping in.

The photo that Vera-Ellen shows to Crosby and Kaye of her brother, Bennie, is actually a photo of Carl "Alfalfa" Switzer of "Our Gang" fame.

Even though Clooney was playing the elder of the two sisters, she was actually seven years younger than Vera-Ellen.

Vera-Ellen did not sing any of the songs in the movie. Trudy Stevens voiced all her songs (except "Sisters," on which Clooney sang both parts).

"White Christmas" was the highest-grossing movie of 1954.
