In the US, a special screening of the film "The Long Walk" based on the book by Stephen King was held, where viewers walked on a treadmill at a speed of at least 4.8 km/h throughout the entire film session. Those who stopped or walked slowly were thrown out of the hall. The strange-looking experiment was a reference to the plot of the film. 
An immersive screening of the film "The Long Walk" was held in Los Angeles. Viewers were put on treadmills and required to maintain a speed of at least 4.8 km/h. Those who slowed down or stopped were thrown out of the hall. In the film based on the book by Stephen King, people were killed for this.
Film plot:
An annual competition called "Long Walk" is held in the country, in which one hundred young people participate. They must walk at a speed of over 4.8 km/h along a given route, after several violations the participant drops out. The winner gets a large cash prize and the fulfillment of all wishes.
According to the participants, several people actually "dropped out" of the race: someone could not keep up the pace, and someone simply did not reach the final due to banal reasons like going to the toilet.
