To say planning a Super Bowl halftime show is a massive undertaking would be a massive understatement.

Only ET has an exclusive sneak peek at how the Super Bowl 50 Pepsi Halftime Show is all coming together, from production design to Coldplay's rehearsals.

"In an ideal world, we'd like to somehow honor the past, celebrate the present and look to the future," lead singer Chris Martin says. "I don't know how we're gonna do that, but we're gonna try our best."

As ET first reported, Beyonce is set to join the band on-stage during the set. Bruno Mars is also expected to join, while the show's production designer, Bruce Rodgers, hints at even more special guests.

"I think Super Bowl 50 is gonna be more special than maybe people realize," he says. "The way that the NFL is going to bring people into the halftime show is gonna be pretty high tech and very, very exciting."

But in the end, all the planning and preparations boils down to less than 10 minutes of set-up time at Levi's Stadium.

"It all just comes down to, you have seven and a half minutes," explains lighting designer Bob Barnhart. "We can come up with the greatest ideas in the world, but it's gotta get on the field in seven and a half minutes and it's gotta work. You're never ready."

Performing in San Francisco creates its own set of unique challenges. According to the video, there's a 50 percent chance of rain expected on Super Bowl Sunday.

"Being such an exposed stadium that it is, the weather's a big factor. It adds more complexities than I could ever wish for," Barnhart says. "The people who say, 'Don't sweat the things you can't control' have never done the Super Bowl halftime show."

Rain or shine, Coldplay will take the stage during Super Bowl 50's Pepsi halftime show on Sunday, Feb. 7.
