Answer 1

You need to check whether a file is there or not before adding movie player also you can add default
-(IBAction)Play:(id)sender
{
NSString *documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES)objectAtIndex:0];
NSString *file = [documentPath stringByAppendingPathComponent:#"xcode4-outlet.mov"];
NSURL *url = [NSURL fileURLWithPath:file];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:file];
if(fileExists)
{
_moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePreloadDidFinish:) name:MPMoviePlayerLoadStateDidChangeNotification
object:_moviePlayer];
_moviePlayer.shouldAutoplay=NO;
[_moviePlayer prepareToPlay];
}
}
Add your movie after movie is completely loaded
-(void)moviePreloadDidFinish:(NSNotification*)notification
{
_moviePlayer.controlStyle=MPMovieControlStyleDefault;
[self.view addSubview:_moviePlayer.view];
[_moviePlayer play];
[_moviePlayer setFullscreen:YES animated:YES];
}

You may not be supplying a valid path to the URL. It looks like your trying to append your resource to the documents path, but that resource may not actually be there. You have to write the file to that path first. You should always double check your path with:
if ([[NSFileManager defaultManager] fileExistsAtPath:yourPath])
{
//path exists
}
Otherwise, just init the movie player with the straight up resource if you have it inside of your app.

Your code looks good. Check the file name is correct.. Also give a try like
-(void)playMovie
{
NSString *documentsDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [documentsDirectoryPath stringByAppendingPathComponent:#"xcode4-outlet.mov"];
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
MPMoviePlayerController *moviePlayerController = [[[MPMoviePlayerController alloc] initWithContentURL:fileURL]retain];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
[moviePlayerController play];
}
- (void)moviePlaybackComplete:(NSNotification *)notification
{
// playback completed
}
