I'm trying to use the Html.DropDownList extension method but can't figure out how to use it with an enumeration.

Let's say I have an enumeration like this:

public enum ItemTypes
{
    Movie = 1,
    Game = 2,
    Book = 3
}

How do I go about creating a dropdown with these values using the Html.DropDownList extension method? Or is my best bet to simply create a for loop and create the html elements manually?
