Well, to know Maya Rudolph's role in 'A Christmas Story', we would need to look closely at the plot. Maybe she plays a character who helps bring out the holiday spirit in the story, perhaps a relative or a neighbor. Without actually seeing the movie or having more information, it's hard to say for sure. But given her comedic talent, she might be there to provide some humorous moments during the Christmas celebrations.
I'm not sure specifically what role Maya Rudolph plays in 'A Christmas Story' without more research. It could be a fun and unique character that adds to the charm of the Christmas - themed story.
I haven't watched this version of 'A Christmas Story' with Maya Rudolph in it. However, considering her acting style, she could potentially play a character that is either the heart of the family during Christmas, like a mother figure who tries to keep everyone together and in the holiday mood. Or she could be a wacky character, like an over - enthusiastic Christmas shopper or a zany aunt who has all kinds of strange Christmas traditions. We really need more details about the movie to be certain.
