"Gotham" is back for a fourth season on Fox. Star Michael Maize plays bad guy Grady Harris on the show, and stops by to tell us all about life on set. Maize says his secret to playing villains is to view them as real people. He also tells us why the show is getting so much traction on traditional network TV during the age of streaming. Plus, we look ahead to Batman's return to the big screen in "Justice League." Maize is also starring in Syfy's new show "Happy." It's about a hitman who befriends an imaginary blue unicorn. Despite its strange concept, Maize says the project is his favorite one he's worked on during a very busy 2017.
