Tetris is based on the real-life bidding war for the Russian video game, but it takes some extreme creative liberties that end up making the movie less entertaining. The AppleTV+ movie follows Henk Rogers, who learns about Tetris and attempts to buy the publishing rights to it, only he finds himself in too deep when he discovers that the rights actually belong to the state of the Soviet Union. In the late 1980s, Russia was still under a communist regime, and citizens couldn't profit from their intellectual property. As a result, Henk works with Tetris creator Alexey Pajitnov to buy the rights from the U.S.S.R.
