Don't you just hate it when aliens take the form of gigantic retro videogame characters and invade the earth, laying waste to everything in their path? No? You actually don't hate that idea?! Well then, this movie is for you.
I have no idea what the conversation went like when this movie idea was put forward, but I suspect it was something like this:
"We want to make probably the best movie in the world. It'll have actual Space Invaders invading from space, and a giant Pac-Man will eat a fire truck. Oh, and the whole thing will be in 3D."
But in all seriousness, if you grew up in the 80's or 90's, or if you just love retro games, you need to see this movie.
