'Transformers: Dark of the Moon' is set to open in theaters on July 1, and now we have a new behind-the-scenes clip from the movie for you to check out. The video show fans how some of the amazing stunts and action sequences were created, and we guarantee you won't believe your eyes.

Director Michael Bay selected a group of precision skydivers to perform stunts in the film after seeing the extreme sportsmen on '60 Minutes' one night. The show featured footage of the skydivers jumping off mountains with the help of wingsuits, which allow the guys to essentially fly (don't worry, they have parachutes, too).
The director took the idea of the skydivers and their special suits and incorporated them into the film, which was shot in Chicago -- a far cry from the open air of the mountains.

"These are actual people flying wingsuits in a downtown city environment, which has never been done before," says Rob Bruce, director of photography for the precision skydiving unit. "So for them it's really nerve-wracking."

But with all of the special effects that were added to the shots, it was so worth it. Check out the behind-the-scenes clip below, and head to Moviefone to watch the trailer for 'Transformers: Dark of the Moon,' which arrives in theaters next month.
