Santa Claus (1985)

Release in 1985. It was the last major fantasy film, produced by the Paris-based father-and-son production team of Alexander and Ilya Salkind. Released in North America on November 27, 1985 by Tri-Star Pictures, the film was a straightforward, nondenominational attempt to explore the mysteries of Santa Claus, the key objective being to answer some of the most basic questions many children have about Santa: How do his reindeer fly? How did Santa and his wife make it to the North Pole? How does he manage to go up the chimneys?
The first half of this film, set hundreds of years ago, shows how the old man who eventually became Santa Claus was given immortality and chosen to deliver toys to all the children of the world. The second half moves into the modern era, in which Patch, the head elf, strikes out on his own and falls in with an evil toy manufacturer who wants to corner the market and eliminate Santa Claus .
