Fan Casting Lex Luthor in Batman: Avenger of The Fallen

During the film, before Bruce runs away to Metropolis to fight General Zod, he first goes to Lex Luthor's cell in Arkham Asylum. The two talk for a while, mostly about the death of Superman and how it's affected both of them, with Lex feeling that Zod stole his victory over Clark Kent away from him, before Batman asks him if he had any plans on how he could have killed Superman. Lex tells Bruce that he had a number of weapons to use against the Man of Steel, including a clone of Superman named Bizarro, a hulking rock-like war beast known as Doomsday, and even a Kryptonite spear he planned on using in battle. With all this in mind, Bruce leaves for Metropolis afterwards.
