How is the FIFA World Cup Final Halftime Show going to pull off performances from BTS, Madonna, Shakira, Burna Boy, Justin Bieber and Gustavo Dudamel and his orchestra in just 11 minutes?

That’s the biggest question heading into the halftime event’s maiden voyage this weekend, and as the show’s executive producer, Guy Carrington of Done+Dusted, tells The Hollywood Reporter, it’s going to come through a tight, highly coordinated mega-mix that’s still got a few more surprises in tow as well.

“Obviously I’m not going to give anything away on the performance itself, but we’ve spent months and months preparing this, developing it and working with all of the artists,” Carrington tells THR.” It’s a carefully curated performance that’s going to be spectacular.”

FIFA had first unveiled the Halftime Show roster back in May, announcing BTS, Madonna and Shakira as the headliners. The organization rolled out even more performers last week, confirming Bieber and Burna Boy’s appearances too, along with Dudamel and the PS22 choir featuring Coldplay.

Coldplay’s Chris Martin oversaw the show’s bookings, as he did for last year’s Club World Cup. When asked about the process for adding Bieber to the mix and when and how that came about, Carrington reiterated it was mainly in Martin’s purview but added that “I think there were conversations happening for a long time.”
