I'm trying to get a basic movie to play in an iPhone app; however, I can't seem to get it to work. Here's my entire code:

#import <MediaPlayer/MediaPlayer.h>
#import "ViewController.h"

@implementation ViewController

- (IBAction)playMoviePressed:(id)sender
{
    NSURL *url = [NSURL URLWithString:@"http://www.ebookfrenzy.com/ios_book/movie/movie.mov"];

    MPMoviePlayerController *moviePlayer =
    [[MPMoviePlayerController alloc] initWithContentURL:url];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(moviePlayBackDidFinish:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:moviePlayer];

    moviePlayer.controlStyle = MPMovieControlStyleDefault;
    moviePlayer.shouldAutoplay = YES;
    [self.view addSubview:moviePlayer.view];
    [moviePlayer setFullscreen:YES animated:YES];
    [moviePlayer prepareToPlay];
    [moviePlayer play];
}


@end

I have one button on screen that calls playMoviePressed when it is tapped. I know that this method is getting called. I have also tried this with .mov and .mp4 local files that I have dragged into xcode.
