It's rather common to overdub a movie or TV show with an ad hoc (usually comedic) soundtrack.
This idea is for a production, authored specifically to produce as many wildly different plots as possible in the same and different languages, using the exact same video footage, but with different soundtracks. All, using the same actors, with the multiple audio recordings done near simultaneously during shooting (to get the ambient sound right) ; the test is to be able to fool lip-readers.
Bonus points if you can run the film backwards, reaudioed - and produce a different (acceptable) result.-- FlyingToaster, Sep 14 2020 Perfect... Good-Looking_20Peop...20Looking_20PensiveHmm... [RayfordSteele, Sep 14 2020] You could use a lot of stock footage from <link>.-- RayfordSteele, Sep 14 2020 Isn't this how the Magic Roundabout was made?-- pocmloc, Sep 15 2020 No, that was fractals.-- RayfordSteele, Sep 15 2020 So ambiguous actions only fully meaningful in audio context? Filming all the lines of one of those decision page number books and not know which film your watching.-- wjt, Sep 15 2020 ^ Well, that would/could be a subgenre, but I had in mind totally unrelated movies, sharing only video.
Sorta like what friends would do when otherwise bored in a coffee shop, mocking another couple at a different table....
"They're spies, didn't you see the microfiche she passed him ?"
"Nope, lovers : they were kissing before they came to the cafe, and she was giving him his gum back..."-- FlyingToaster, Sep 16 2020 Ah yes, the decision paths are totally different genres.
To have this work, it needs to rest on subtle missing information, like not accurately knowning what was passed, to allow the freedom of multiple plots. A bit like train crossing tracks.-- wjt, Sep 17 2020 random, halfbakery
