Cameron Monaghan wears a straight jacket while playing a young version of The Joker on the set of Gotham on Wednesday (July 8) in New York City.
The 21-year-old actor was seen throwing gasoline on to a school bus full of students.
Cameron‘s co-star Ben McKenzie was seen on set the day before while filming scenes and he was covered in fake blood! See the pictures in the gallery below.
A few months ago, Cameron talked about how he found the laugh for his character Jerome, who later turns into The Joker.
“I’m surprised my neighbors didn’t call the cops on me because I spent those weeks constantly laughing and staring at myself in the mirror,” Cameron told Comic Book Resources. “Even if I was driving in my car to get food or something, I was repeating the monologue. I allowed myself to be a crazy person.”
