This is the "MGM Christmas Trailer" from 1937, which is available as a bonus on the Warner DVD of the 1938 film A Christmas Carol. It runs for 90 seconds approximately, starts off with showing us a snowed in house and it also ends this way. In-between, we see Judy Garland and a church choir. They perform "Silent Night, Holy Night" for the audience. I think this was a nice little present by MGM for audiences and I personally enjoyed the watch. However, I must say I saw this for the first time several years ago and I liked it more back then than I do today. Garland's voice is really deep and this may not be to everybody's liking. I think she was 15 when this was made and probably the biggest (female) star at that time from her age group. This is from 2 years before she made her eternal "Wizard of Oz" film. All in all, I liked this one here more than the other MGM Christmas short film "The Christmas Party" from 1931, in which Jackie Cooper invites all his buddies. The reason may be that the song in here is just such a classic. Always has been, always will be. I recommend the watch, preferably in December.
