The limited theatrical run comes about two years after the release of “Taylor Swift: The Eras Tour,” which was the biggest opening weekend for a concert movie ($93 million domestically) and the highest-grossing concert movie domestically ($180 million), according to Box Office Mojo. Eighty percent of Swifties said they “formed deep friendships” because of Swift, according to research firm The Harris Poll. Both Swift and AMC saw a windfall from “The “Eras Tour” movie. Swift — whose net worth has inflated to $2.1 billion, according to Bloomberg’s Billionaire Index — first reached billionaire status during the “Eras” tour. She received 57% of the ticket revenue from “The Eras Tour” movie, of which AMC took a small distribution fee.
