A two hour-long movie featuring colorful moving blocks would either be boring, or the most intense experience ever!
Just imagine the anxiety you'd get by watching a block slowly move down the screen and having no control over it.
You'll constantly be frustrated not knowing if it'll land on the right spot, and when it does, the whole theater will clap and cheer.
Just kidding. A "Tetris" movie would be the worst thing ever and it'd be a bigger flop than Disney's "John Carter." However,Threshold Global Studios is working on an $80 million film adaptation of the iconic video game Tetris.
