Rebecca Rubin Film and Media Reporter Taylor Swift‘s “Eras Tour” concert film is projected to open to $100 million at the domestic box office, but the final weekend number will likely be much bigger. The movie, a cinematic rendering of the pop star’s record-breaking, three-hour stadium tour, looks to generate up to $125 million from approximately 3,850 theaters in North America, according to early estimates. It’s also expected to add $30 million to $50 million from 4,150 venues internationally in more than 90 countries for a global start upwards of $150 to 175 million.
