I got a specific titantron envisaged in my mind.
The song doesn't begin until the initial drop, where it flashes the wrestler's name across the screen with the whole arena dimmed. When Bono's vocals kick in, it cuts to the guy standing in the middle of a tall grass field with stormy clouds overhead. Rain is pouring, although not too much and he just stares directly into the camera. He does that chin up thing a lot of wrestlers do as the camera cuts back and forth. Imagine Brock Lesnar's titantron where he just poses, punches and makes angry faces in obvious roid-rage inside a darkened room, before you get fight clips (the guy's going to be a high flyer by the way) that accompany from the second verse through to the chorus. The wrestler will have made his way to the ring by 1:30 in the song and begins to go to the corner turnbuckles, standing up on them with his arms in the air like The Rock, SCSA etc. did back in the day. While in the ring the wrestler does some shit like Triple H does with the water, just cool simple tricks to wow the audience. Maybe when Bono talks about playing cards he can whip a deck out of his pocket or a hat and throw them out in a pattern, showering the arena with cards. The song finishes at the guitar solo around 3:20 in.
