1984. The gaming business is on the verge of exploding. Stefan Butler is working on turning the interactive adventure book Bandersnatch into a game.
In the book, the reader is presented options which make on which page (s)he continues reading. Thus Butler is making a game with the same options. Typing commands has been done before, he just gives two option to choose from using the joystick.
The film is made the same way. When you go along you have to choose what to eat for breakfast, to drown the computer or smash it, etc. thus giving an alternative turn to the story.
The first time I navigated myself to an end within the hour. The second time I noticed that most other options are just small loops back, but there are so many loops that I started going in circles, so at one point I just turned it off without trying to find out any of the alternative endings (which I somewhat doubt there are (m)any).
Nicely thought off, but it makes a fairly dull film with only here and there an amusing twist/loop.
