What could we add to "The Hobbit" to make it FOUR movies?

Add a love interest for Bilbo. Take a break from the story and have him romance her and show off by trying to ride a cow.

That would have to be titled Mordor Strikes Back!

Brokeback Deagol. Did you really think it was just about the Ring?
