The idea of making such old games like Asteroids and Space Invaders into movies confuses me.
For one, these games have virtually no story. There are no protagonists, antagonists, or any characters for that matter. We just have moving pixels with no feelings or personalities. There's nothing to work with. Then movie won't be able to last a minute without adding new things to the story. And it has to stretch itself out to be at least an hour long, so who knows what they're going to do to accomplish this. Basing movies off of an incredibly dated game always has you running into the problem of having to re-imagine all of those old pixel graphics in the modern age of cinema, probably with 3D as well.
What you end up with is something that only resembles the original game in an incredibly vague way. It won't be a Space Invaders movie, it will just be a movie called Space Invaders. And what's the point of that? To sell the movie based on the name? The first problem I see with that is that many people don't know or remember what Space Invaders is. The second problem is that everyone who does remember what it is know that you can;t make a movie out of Space Invaders. So really, what's the point? To attract attention based on the fact that you're making an old game into a movie? That's not really the best publicity as tons of people won't give a toss about that, and in the end you're just setting yourself up for failure.
Look at the Super Mario Bros. movie. Despite the time it was made in, it still failed horribly. Mostly because the story for Super Mario Bros. was so bare that the directors had almost nothing to work with. The result was something that only vaguely resembled the Super Mario Bros. game. Now imagine what they are going to do with Space Invaders, an even older game with the most primitive story imaginable.
