Call Me Claus is a 2001 Christmas film that stars Whoopi Goldberg as Lucy Cullins, a TV producer who has lost her Christmas spirit. She is approached by a man named Nick (Nigel Hawthorne), who claims to be Santa Claus and that he needs to find a replacement for him since he's retiring. Lucy initially thinks he is crazy and dismisses him, but as she begins to experience some unusual events that draw her closer to Nick, she starts to believe he is the real Santa.
Nick sets Lucy a series of challenges to prove that she has what it takes to be the next Santa Claus, and as she passes them, she starts to rediscover the joy of Christmas. However, there are forces at work that are determined to ruin Christmas, and Lucy and Nick must work together to prevent a grinch-like figure from stealing the holiday spirit altogether.
As Lucy tries to complete the challenges set by Nick, she adopts several of his practices and behaviors. These include wearing the iconic red suit of Santa Claus, signing greeting cards with "Ho Ho Ho," and using unconventional transportation options such as flying reindeer to deliver presents.
Ultimately, Lucy completes the challenges and takes up the mantle of Santa Claus, delivering happiness and joy to families all across the world. The film ends with Lucy passing the torch to another deserving person, ensuring that the magic of Santa Claus will continue for generations to come.
