Why not instantiate the repository like this?

Is there a reason to use the constructor rather than do it like so?

private MovieRepository _movieRepository = new MovieRepository();

This code seems to work just as well for me?

Instead of:

        private MovieRepository _movieRepository = null;

        public MovieGalleryController()
        {
            _movieRepository = new MovieRepository();
        }

There's no functional difference between these, the reasons for choosing one over the other would depend on the larger context. If you have other needs for a constructor, assigning in the constructor might be more consistent. But otherwise inline initialization could save you from needing an explicit constructor at all.
