Answer 1

You should map your DB (MoviesData) model To Bussiness model (MovieViewModel)

   public ActionResult Details(int Id = 1)
    {
        MoviesData movie = db.MoviesData.Find(Id);
        MovieViewModel MovieVM = new MovieViewModel();
        MovieVM.MovieID = movie.MovieID;
        MovieVM.MovieName = movie.MovieName;
        MovieVM.MovieDescription = movie.MovieDescription;
        MovieVM.MovieCategory = movie.MovieCategory;
        MovieVM.MovieYear = movie.MovieYear;

        return View(MovieVM);
    }

Answer 2

In your ActionResult Details method db.MoviesData.Find(Id) returns object which type is WebApplication3.Models.MoviesData but your variable type is MovieViewModel. That's why you are getting exception.

You need to cast manually. So, You can code like this,

public ActionResult Details(int Id = 1)
{
    MoviesData movie = db.MoviesData.Find(Id);
    MovieViewModel MovieVM = new MovieViewModel{
        MovieID = movie.MovieID,
        MovieName = movie.MovieName,
        MovieDescription = movie.MovieDescription,
        MovieCategory = movie.MovieCategory,
        MovieYear = movie.MovieYear
    };

    return View(MovieVM);
}
