There is no work on exactly how they are going to translate this to film. The choices are:
1- Make patrons walk from theater to theater based on their choices – “If you want to find the Ruby Skull, go to Theater #3. If you want to battle the Fire Gnomes, go to Theater #5”
2- Do a sort of Run, Lola, Run style film, where we see events play out multiple times based on different choices (which would result in multiple bad endings that we can just reset!) Make the main character a precog or something, but different than that Nic Cage movie.
3- Do a campfire round table similar to Rashomon, with characters telling the same events with different choices. (hat tip to @RacattackForce)
4- Invent some sort of device where the audience votes on what happens next, like was in Futurama and I think was an actual gimmick for a real movie (and the voting machines did nothing, IIRC. I can’t find any information on if I am remembering this correctly!)
5- Ignore the choice aspect entirely, become a generic film. The safest and lamest solution.
Besides the lack of information on how they will pull it off, there is no information on which of the many many books they will be using (if any), which offer a dream choice of almost any genre imaginable.
I do hope they at least have monsters show up, like this one I remember: The Abominable Snowman. Because we need more monsters in films! Whatever they choose for Choose Your Own Adventure, it better be the correct ending!
