Taylor Swift is giving one last glimpse of her Eras Tour concert documentary before its official release. "On December 12, every new song, every new moment [and] everything you've waited for," a trailer shared via Disney on Monday, December 1, read, as Swift, 35, performed The Tortured Poets Department tracks during her tour. "Including a new acoustic set." Elsewhere in the trailer, Swift spoke directly to her fans. "We've had so long to prepare for the end of this tour, and we get to play one last show for you here tonight," she gushed.
