Movies like The Last Showing

At the start of the movie, there is little or no sound telling the viewer what is happening, but there seems to be a party with young people, and there is a movie theater. In England, Martin and Allie are a young couple out on a date. He gives her jewelry and then takes her to a multiplex with 12 theaters. Their plan is to watch a horror movie. What they don't know is they are about to be in one. Stuart is not at the concession stand like he is supposed to be. He is actually in a room where he can watch footage on security cameras. His boss Clive is not happy. He tells Stuart to run the concession stand, and Stuart says there is something wrong with one of the movies. Clive said Stuart is not qualified to fix it because he hasn't had the training in digital movie technology, and that is why after more than 20 years, he is also no longer the projectionist. Stuart protests that he is smart enough to continue as the projectionist, and to fix whatever needs fixing. Still, Clive is the boss. But as we see throughout the movie, Stuart is brilliant at dealing with new technology. The couple buys their popcorn. There is something wrong with the lemonade, as Allie discovers when she tries some. Stuart has actually tampered with it. And the adventure begins.
