foto de DB Meu banco de dados tem 3 tabelas Customers, Films e CustomersFilms, agora é a tabela entre filmes e clientes. Quero exibir uma tabela de cutomers com os filmes que eles alugaram. Eu escrevi uma função que faz o trabalho para identificação específica (no código 8 e 9). Minha pergunta é como mostrar os dados para todas as entidades?

   public ActionResult GetData()
    {
        MyDatabaseEntities2 db = new MyDatabaseEntities2();
        var q = (from c in db.Customers
                 from Films in db.Films
                     where Films.FilmId == 8
                     where c.CustomerId == 9
                 select new
                 {
                     c.CustomerName,
                     c.Phone,
                     c.FilmId,
                     c.CustomerId,
                      FilmName = Films.FilmName

                 }).ToList();
        return Json(new { data = q }, JsonRequestBehavior.AllowGet);
    }
