AMC Theatres announced a list of rules that Taylor Swift fans must follow while attending screenings of the Eras Tour concert film, which opens this weekend. The company's website says “Eras attire and friendship bracelets are strongly encouraged,” as is “dancing and singing” so long as it doesn't block the aisles or anyone's view of the screen. AMC also says “feel free to take selfies and group photos,” but don't pirate the movie, which runs 2 hours and 48 minutes. Taylor Swift: The Eras Tour is expected to open with around $125 million at the North American box office, and could add another $50-$75 million internationally from the 90 other countries where the film is being released. By the end of its run in movie theaters, it's expected to rank among the top 10 biggest blockbusters of the year for 2023.
