Movies based on video games? Has there ever been an actual good one?
For my tastes, I’d think it should be a good movie, as a movie. But those are pretty rare these days.
I think before asking what guidelines to follow, one would want to answer why one is making a movie based on a video game, which could lead to reasoning about guidelines.
Yes some people like or didn’t hate some video game movies, but what are those peoples’ standards, and do they match your own standards/tastes/goals?
It seems to me the usual reason such a film is made is because someone pitched the idea and got it accepted by a studio, based on the idea it would sell based on the brand. The choices then tend to be based on what the pitch was and what parts the people involved care about.
If you’re just thinking of doing it as a personal project without investors, then it’s more up to what you care about.
It probably depends on the game and its fans too, how much people will care about which kinds of details.
Only two films come to mind that others have said were decent films based on video games:
One is Doom, which I have read reviews of but not seen. The game Doom is a pretty low-background shoot ‘em up game based in a surreal hell world. The movie invented its own sci fi story that was not the same. But it tried to take several things from the game that it could work into its minimal sci fi story.
A more recent and larger success, I hear, was last year’s Sonic The Hedgehog film. You could research what that was like.
