Ed Sheeran may be the single commanding force when he takes the stage at big arenas like Wembley, which seats 80,000, but behind the scenes, he's still just a nervous guy wondering how he's going to play to thousands of people.

Ed's new concert doc, "Jumpers For Goalposts," will explore exactly that -- the dude behind the confident show. The trailer for the film was placed subtly in our laps on Thursday (Sept. 17).

There are cute moments -- like when you see couples cuddling to his music -- and then here are some nail-biters -- like when you see fans running toward the stage.

"My dream last year was to play Wembley," Sheeran said in one scene, cutting into a guitar-shaped birthday cake. "Now it's come to it and reality's hit, and now you're like, 'I have to play to 240,000 people.'"

Back in July, Ed played three sold-out shows at Wembley Stadium, where Elton John joined him for his last night. You see a glimpse of Ed meeting Elton in the trailer.

"Jumpers For Goalposts" will be in select theaters Oct. 23 through Oct. 25.
