Vince Vaughn's character in A Christmas Story Christmas was Mr. Parker. He brought his own charm and interpretation to the role, making it memorable for viewers.
Yes, he has. Vince Vaughn was in 'Fred Claus'. In this movie, he played the role of Fred Claus, Santa's brother. It's a fun take on the Christmas story, with Vince Vaughn bringing his own brand of humor to the character. It's a family - friendly movie that adds a different perspective to the whole Santa Claus and Christmas lore.
I'm not sure specifically what role Vince Vaughn played in 'A Christmas Story' as he may not be a very prominent or known actor in relation to this movie. Maybe it was a small or cameo role that I'm not aware of.
