    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterFullScreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullScreen:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFinishPlayback:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

    [self.moviePlayerController setContentURL:someExistingURL];

        // "self" is a UIViewController subclass, and is presented as a "fullscreen" modal view controller from its parent
        // I'm setting the movie player's view's frame to take up the full rectangle of my view controller, but really …
