Writer/director Alexis Kirke is taking choose-your-own-adventure filmmaking to the next level. His short film, "Many Worlds," has four different endings that will be determined based on the audience's physical response to the film. Several members of the audience will be fitted with sensors that detect their heart rate, brainwave activity, perspiration, or muscle tension. The film branches out at certain points and will take a path depending on how tense or calm the audience members are registering.
Explains The Verge, "So long as you can get on board with a found-footage thriller about a high-school science chestnut, the conceit is fairly interesting: if an audience gets bored during a slow section, the next segment will speed up; if they're 'too happy,' the next section might be meant to depress them."
