A Martian Christmas on AllMovie

A group of Martian invaders discovers that mankind may not need to be wiped out after all when they touch down on planet Earth just in time for Christmas. Far in the deepest reaches of the cosmos, a device made by earthlings scours the solar system for new forms of life. When a race of highly advanced aliens discovers the device and assumes that an invasion is imminent, they decide to launch a pre-emptive counter attack. But there's a stowaway on their Earthbound ship, and he's a curious eight year old Martian named Kip. The son of the ship's commander, Kip only wanted to spend a little more time with his dad and never meant to jeopardize the mission. When Kip accidentally activates an escape pod than sends him plummeting down to Earth, his dad quickly follows for fear that his son will be stuck on the surface when the planet is vaporized. But Kip and his father are in for a big surprise, because once they experience the joy of the holiday season, they realize that their assumptions about the human race were totally unfounded, and that the invasion should be called off immediately.
