Something is wrong with the syntax and I can't see it. Please help!

Watch de video several times now. I can't find the error. Any ideas?

VideoGamesController.cs 
using System.Web.Mvc;
using Treehouse.Models;

namespace Treehouse.Controllers
{
    public class VideoGamesController : Controller
    {
        public ActionResult Detail()
        {
            var videoGame = new VideoGame()
            {
                Title ="Super Mario 64",
                Description="Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64.",
                Characters = new Characters[] { "Mario", "Princess Peach", "Bowser",  "Toad", "Yoshi"},

           };
            return View(videoGame);
        }
    }
}
Detail.cshtml 
@{
    ViewBag.PageTitle = "Video Game Detail";
}

<h1>@ViewBag.Title</h1>

<h5>Description:</h5>
<div>@ViewBag.Description</div>

<h5>Characters:</h5>
<div>
    <ul>
        @foreach (var character in ViewBag.Characters)
        {
            <li>@character</li>
        }
    </ul>
</div>
VideoGame.cs 
namespace Treehouse.Models
{
    // Don't make any changes to this class!
    public class VideoGame
    {
        public int      Id { get; set; }
        public string   Title { get; set; }
        public string   Description { get; set; }
        public string[] Characters { get; set; }
        public string   Publisher { get; set; }

        public string DisplayText
        {
            get
            {
                return Title + " (" + Publisher + ")";
            }
        }
    }
}

The preview can be helpful. In this case, one of the errors displayed was a good clue: "The type or namespace name `Characters' could not be found."

This happened when the type of the "Characters" array was changed to type "Characters". That is not a defined type, and those items are still of type "string" (as defined in "VideoGame.cs").
