Не могу получить модели на бэк из view по связи many-to many в приложении MVC

Помогите, пожалуйста, разобраться с проблемой. Делаю проект Movie. БД подключал через CodeFirst подход. Есть модели со связями many-to-many (к примеру Actor и Movie). После реализации контроллера с методом create, при создании нового фильма, во вьюшке не могу получить данные, т.е. у меня отображаются доступные актеры, но я не могу их выбрать, фильм создается с пустыми данными. Но если прописать связи напрямую в БД (через SQLManager, что ActorId = 1 принадлежит MovieId = 3), то все срабатывает.

вот каким кодом пытаюсь это получить модели

    public class Actor
{
    public int ActorId { get; set; }

    [Required(ErrorMessage = "Full Name is required")]
    [StringLength(50, MinimumLength = 3, ErrorMessage = "Last name cannot be longer than 50 characters and less 3.")]
    [Column("FullName")]
    public string FullName { get; set; }

    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)]
    public DateTime DayOfBirth { get; set; }

    [Required(ErrorMessage = "Image is required")]
    public string ImageUrl { get; set; }

    public string Biografy { get; set; }

    //movies
    public virtual ICollection<Movie> Movies { get; set; }
   }

 public class Movie
{
    public int MovieId { get; set; }

    [Required(ErrorMessage = "Title is required")]
    [Display(Name = "Title"), StringLength(60, MinimumLength = 3)]
    public string Title { get; set; }

    [Required(ErrorMessage = "Image is required")]
    public string ImageUrl { get; set; }

    [StringLength(500, MinimumLength = 3, ErrorMessage = "Descriptipn cannot be longer than 500 characters and less 3.")]
    public string Description { get; set; }

    [Display(Name = "Release Date"), DataType(DataType.Date)]
    public DateTime ReleaseDate { get; set; }

    //Genre
    public Genre Genre { get; set; }

    //Rating
    public Rating Rating { get; set; }

    //actors
    public virtual ICollection<Actor> Actors { get; set; }

    //producers
    public virtual ICollection<Producer> Producers { get; set; } }

Контроллер с методом Create

 public class MoviesController : Controller
{
    private readonly IMoviesRepository _service;

    private readonly IProducerRepository _producer;

    private readonly IToastNotification _toastNotification;


    public MoviesController(IMoviesRepository service, IToastNotification toastNotification, IProducerRepository producer)
    {
        _service = service;

        _toastNotification = toastNotification;

        _producer = producer;
    }

    // GET: Movies/Create
    public async Task<IActionResult> Create()
    {
        var movieDropdownsData = await _service.GetMovieDropdownsValues();

        ViewBag.Producers = new MultiSelectList(movieDropdownsData.SelectedProducers, "ProducerId", "FullName");
        ViewBag.Actors = new SelectList(movieDropdownsData.SelectedActors, "ActorId", "FullName");

        return View();
    }

    // POST: Movies/Create
    // To protect from overposting attacks, enable the specific properties you want to bind to.

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Create([Bind("MovieId,Title,ImageUrl,Description,ReleaseDate,Genre,Ratin,ActorsId,ProducersId")] Movie movie)
    {
        if (ModelState.IsValid)
        {
            await _service.AddAsync(movie);

            _toastNotification.AddSuccessToastMessage("Movie created");

            return RedirectToAction(nameof(Index));
        }
        var movieDropdownsData = await _service.GetMovieDropdownsValues();

        ViewBag.Producers = new MultiSelectList(movieDropdownsData.SelectedProducers, "ProducerId", "FullName");
        ViewBag.Actors = new SelectList(movieDropdownsData.SelectedActors, "ActorId", "FullName");

        return View(movie);
    } }

вот вьюшка на создание фильма

@model WebAppMovie.Models.Movie

@using WebAppMovie.Data.Enums
@using WebAppMovie.Data


@{
  ViewData["Title"] = "Create a new movie";
 }

        var output = document.getElementById('ImagePreview');
        output.src = $(this).val();
     })
    </script>
     }

ну и как пытаюсь связать Movie с Actor

public async Task<NewMovieDropdown> GetMovieDropdownsValues()
    {
        var response = new NewMovieDropdown()
        {
            SelectedActors = await _context.Actors.OrderBy(n => n.FullName).ToListAsync(),
            SelectedProducers = await _context.Producers.OrderBy(n => n.FullName).ToListAsync()
        };

        return response;
    }

    public class NewMovieDropdown
    {
        public NewMovieDropdown()
        {
            SelectedProducers = new List<Producer>();

            SelectedActors = new List<Actor>();
        }

        public List<Producer> SelectedProducers { get; set; }
        public List<Actor> SelectedActors { get; set; }
    }

создаю таблицы в БД

public class ApplicationDbContext : IdentityDbContext
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
    {
    }
    public DbSet<Actor> Actors { get; set; }
    public DbSet<Movie> Movies { get; set; }
    public DbSet<Producer> Producers { get; set; }
    //public DbSet<Score> Scores { get; set; }
    public DbSet<Person> Persons { get; set; }
}

Буду благодарен за любую помощь. Спасибо.
