We also watch Miracle on 34th Street, with Natalie Wood, Maureen O'Hara, John Payne and Edmund Gwenn, in black and white (the best way to watch it). Note: Edmund Gwenn won a Best Actor in a Supporting Role Oscar for playing Kris Kringle in Miracle on 34th Street.
We also enjoy watching those "Hallmark Christmas" movies on Netflix.
And like you, Grant, we enjoy watching the first The Thin Man movie, which takes place over the Christmas holiday. Note, however, that it wasn't Maureen O'Hara that was in that film, but Maureen O'Sullivan. Still, The Thin Man is an incredibly good film even today, given the fact that it was released in 1934.
I'll mention one more, that isn't a Christmas related movie, but a New Year's Day related movie. The next Thin Man movie starring William Powell and Myrna Loy, is After the Thin Man. This is, in my opinion, the best of the Thin Man movie series starring William Powell and Myrna Loy as Nick and Nora Charles. It takes place over the New Year's Day holiday. And it stars a very young Jimmy Stewart in one of his earliest roles.
