What's the problem? 
Here is my code that should play a movie when my button is pressed:

    -(void)playMovie:(NSString *)fileName   
    {
    NSString *movieFile = [[NSBundle mainBundle] pathForResource:fileName ofType:@"mov"];
    NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:movieFile];
    MPMoviePlayerViewController *tempMoviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
    MPMoviePlayerController *moviePlayer = [tempMoviePlayer moviePlayer];
    
    [tempMoviePlayer.view setFrame:CGRectMake(0, 0, 1024, 768)];
    [_zoomImageView addSubview: tempMoviePlayer.view];
    [self presentMoviePlayerViewControllerAnimated:tempMoviePlayer]; 
    [self setWantsFullScreenLayout:YES]; 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playMovieFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
    [moviePlayer play];
  
    [fileURL release];
    [tempMoviePlayer release];
    }
