I don't see how the movie would work. We lose when the aliens reach the ground.
Space Invaders: The Movie
Producer Lorenzo di Bonaventura, who has so successfully transformed the toys Transformers and G.I. Joe into box office juggernauts, is next turning his focus towards turning the classic arcade game Space Invaders into a film.
Notes The Hollywood Reporter, "One of the first video games, Space Invaders is credited with taking the medium from a sideshow attraction to a mainstream obsession. The shooter game was technically released in 1978 but made its pop culture mark by the turn of the decade. It featured rows upon rows of aliens (or their ships) raining laser death upon a lone player who took cover behind slowly disintegrating blocks. There have been other rumored attempts to develop a film but none has gone anywhere. With Space Invaders, the producers are facing an interesting challenge: The video game doesn’t have a built-in mythology, so on one hand a film won’t risk offending game fans. Conversely, coming up with a captivating universe, especially for video game adaptations, is no easy task."
