1. He meant Michael Keaton
2. Lex Luthor is Superman's #1 villian. Human, Rich, a genius. He's basically an evil/corrupt version of Tony Stark, who is jealous of Superman and power hungry. And has made many suits of power armor over the decades. The guy you are thinking of is: Wilson Fisk "The Kingpin", and he is also from Marvel and not DC. Lex Luthor is Superman's #1 enemy of all time, and is also a bald, rich badguy... But not nearly as huge as the Kingpin is made out to be by some artists. Their big difference, is that Fisk is a crime boss, and Luthor is a businessman. (A very corrupt and evil business man at that)
3. Daredevil is a blind human with enhanced senses who fights crime, and is also a lawer. He belongs to marvel, and is getting a new series on Netflix. He was also played by Ben Affleck in a live action movie. Daredevil will not be in the Batman v Superman movie (again, he is a Marvel character), but Ben Affleck who has PLAYED Daredevil in a movie already, is Batman in the new movie.
