Spiritual prequel to Prancer and Prancer Returns
There is a 1972 Christmas film called The House Without A Christmas Tree. I consider this film to be the spiritual prequel to Prancer and Prancer Returns.

There is no reindeer but otherwise the film is very similar to Prancer and to a lesser extent Prancer Returns. The entire film is on Youtube. Here is a link to the playlist:

You should watch this film, the reviews and ratings are high and it's one of the greatest films I've ever seen! Who here has seen this? O:-)
