  <p>My goal is to create a customized MPMoviePlayerController looks like above. </p>
  
  <p>The status bar's background has been changed, and the other thing is it shows the "Done" button even when the player is still loading the movie so that the user can cancel the loading (normal behavior of MPMoviePlayerController is to show the "Done" button after the movie starts to play). Believe it or not, the (*) is the activity indicator. </p>
  
  <p>I may be wrong, but I think I read somewhere in Apple's document that one can't modify any of the subviews of MPMoviePlayerController, so I'm wondering if anyone has done anything like this before? </p>
