Here's the closest you'll ever get to being Superman.  A special effects company in L.A. used a remote control helicopter and a GoPro camera.

 

 

And they superimposed arms into the video, so it looks like you're Superman flying around Los Angeles helping people.  It's actually REALLY well done.

 

 

(Search for "Superman with a GoPro."  He starts flying at :21, stops some bad guys at :47, saves a woman from a fire at 1:26, and returns the GoPro to its "rightful owner" at 2:19.)
