I saw a film in school around the 1980's. I think it was a scholastic 8 mm movie . It was called "Zero Hour" . It was about a group of kids playing a game "invasion". The main character is a little girl named Ming. It was set in the future. The game takes a twist and ends up being a real alien invasion. The children join forces with the aliens to off their parents . I also believe it is based on a Ray Brayburry short story. Any information on this film would be great.

It was based on a Ray Ray Bradbury short story, and adapted for three TV series. "Lights Out": http://www.uk.imdb.com/title/tt0632411/, "Star Tonight": http://www.imdb.com/title/tt0708410/, and a Ray Bradbury Theater episode: http://www.tv.com/the-ray-bradbury-theatre/zero-hour/episode/110351/summary.html. I'm not sure where you can watch or buy it though.
