Taylor Swift is giving fans a peek behind the curtain of her upcoming Eras Tour docuseries, which itself is a peek behind the curtain of the biggest tour of all time.

On Thursday (Nov. 13) — exactly one month before the pop star’s 36th birthday — Swift unveiled the full trailer for The End of an Era, a six-part look at how she executed her global Eras Tour coming to Disney+ next month. In the two-and-a-half minute clip, we see the mechanics of how she pulled off everything from her surprise entrance on stage (by rolling up in a faux custodial cart) to how she traveled underneath her unbelievably long catwalk (on a speedy moving platform that launched her back and forth between numbers).

“I’m very aware of mysterious forces at play that I will never have any control of,” Swift says at the beginning. “This show created a bonding experience for, like, 70,000 people all at once. There’s something very special about that.”

The trailer also shows many of the countless people who also played a big role in the two-year trek, which ran throughout 2023 and 2024 and generated a record-shattering $2,077,618,725 in grosses. One of them, of course, is Swift’s now-fiancé professional football player Travis Kelce, who we see on the road with the 14-time Grammy winner both in person and in spirit. In a couple of scenes, Swift cheers him on while watching Kelce’s Kansas City Chiefs’ games on TV, and in another, her mom, Andrea, says of her future son-in-law, “He brings a lot of happiness.”

In a different scene, Travis crouches beneath the stage and greets Swift with a booming “Tay Tay!” before the pair ride off together on the moving platform. Sharing the trailer on her Instagram, the singer wrote, “Honestly can’t think of a better way to celebrate my (almost) birthday than to relive the Eras Tour with you! This time we’re going backstage.”

The full trailer comes exactly one month after Swift first shared a shorter teaser for the Eras doc, and about one month ahead of the project’s Dec. 12 premiere on Disney+. It is expected to give Swifties the most in-depth look at the trek yet, though the historic run was also documented in an Eras Tour concert film in 2023.

Also in the new trailer, Swift rehearses how she’s going to surprise her crowds with various surprise guests, including Sabrina Carpenter — with whom she maps out how she plans to call her on the phone from on stage — and Ed Sheeran, who practices guitar next to his longtime friend and collaborator on a couch. The pair were just a few of the several guests Swift shared the stage with at different points in the tour, along with Jack Antonoff, Aaron Dessner and Gracie Abrams.

With a glint in her eye, Swift says at one point in the trailer, “I love having a good secret.”
