Santa Claus: The Movie is a pretty bold title, if you think about it. The application of "The Movie" after a title implies that what you are witnessing is the one and only definitive cinematic statement on the subject preceeding the colon. Sure, there may be other filmed attempts at the subject, but this is the one. THE one. You have to be pretty sure of your mastery of the subject before slapping a "The Movie" on there. Or you have to be Alexander and Ilya Salkind, the producers of Superman: The Movie and this film.
With a subject like Santa Claus, there is a lot of ground to cover in film. Who he is, how he came to be who he is, how the annual gift-giving works, how the reindeer fly, etc. This is where SC:TM really shines. The first half or more of the movie follows an ordinary 13th century (or so) man named Claus as he and his wife are taken in by the elves and he transforms into the Santa Claus we all know.
There are ancient beardy elves, there's a prophecy, there are muted primary colors, and there are montages a-plenty. One by one, the Santa F.A.Q. entries are ticked off as we see the backstory come together over the passing centuries. The origin story presented here is cheery and heart-warming and makes you want to believe that this is the way the "real" Santa Claus came to be.
But then, somewhere past the half-way point, SC:TM comes to realize another aspect inherent in calling yourself "The Movie" - you should probably have a plot. And that's where things go downhill a bit.
It seems that one of the elves - Patch (Dudley Moore) - has a knack for tinkering outside of his normal toy-making duties. He convinces Santa to let him build some automation into the North Pole manufacturing process. Things go fine until the toys - lacking the quality control that comes with handcrafted toymaking - fall apart on Christmas day. For the first time in all the years, Santa's operation receives returns, in the form of broken toys sent up the chimneys from whence they came.
The humiliated Patch quits and strikes out on his own in the "real world," hoping to do something impressive to get back into Santa's good graces. He tracks down the corrupt and maniacal head of the BZ Toy Company, Mr. B.Z. (John Lithgow), and offers to make something amazing that can given away under the BZ Toys name - lollipops that cause the eater to float in mid-air.
With the success of the Patch Pops, B.Z. insists that Patch up the ante with a stronger batch of the flying candy recipe made into candy canes that BZ Toys can sell in March under the banner of "Christmas 2." The unscrupulous B.Z. pushes ahead with the candy canes despite evidence that they explode when exposed to heat. It's up to Santa Claus, an irritating street urchin, and B.Z.'s step-niece (?) to save Patch and put a stop to the nefarious B.Z. before it's too late.
John Lithgow is great as the over-the-top villain when the movie finally gets around to that part of the story, and Dudley Moore makes for an affable elf. Best of all, David Huddleston (who played the title character in The Big Lebowski) absolutely embodies Santa Claus. Once you've seen him in the full red suit, no department store Santa will ever measure up.
Maybe I see it through nostalgia-colored glasses, but I think SC:TM is a pretty good Christmas flick. It's aimed at children, and its faults are more apparent when seen as an adult, but overall it's charming and fun.
