The Space Invaders movie is apparently on its way. Warner Bros launched the project by putting Greg Russo in charge to write the script.
The movie will probably be loosely based on the game, considering that it is an Arcade game with the only purpose to shoot aliens spaceships.
Greg Russo is actually a busy man in term of adaptation because he is already in charge to finish the Mortal Kombat Reboot. He is also working on the Death Note 2 for Netflix and a Saints Row adaptation. It is hard to judge now his qualities as a writer because of his small filmography, and it is a bit curious that so many projects have been giving to him before he can actually make his mark. However, I really hope that he will succeed in all those projects.
