Santa Claus Conquers the Martians/Headscratchers


 * Why doesn't Chochem volunteer to be Santa Claus, besides the fact that otherwise there would be no movie? He's already a wise immortal being, possibly with supernatural abilities, who cares about the well-being of Martian children. In any case, he probably would do a million times better job being in charge of delivering presents to every child on the planet than the "laziest man on Mars."
 * But he wasn't, as I recall, very jolly. Dropo may have been lazy, but I think the movie was trying to imply that it was because he didn't have anything he really cared about. If he cares about being Martian Santa, he'll probably stop being so lazy.
