Cameron Monaghan Interrupts 'Gotham' Panel at Comic-Con 2015 as the Joker!

The cast of Gotham gets together for a portrait session at the Getty Images Portrait Studio held during 2015 San Diego Comic-Con at Hard Rock Hotel San Diego on Saturday (July 11) in San Diego, Calif.

Earlier in the day, the cast – Ben McKenzie, Sean Pertwee, David Mazouz, Camren Bicondova, Robin Lord Taylor, Cory Michael Smith, and Erin Richards – participated in a panel.

During the panel, Cameron Monaghan, who is playing the Joker next season, showed up out of nowhere and stole the microphone from a fan before being escorted out of the room by security!

That same day, Ben hit up SiriusXM radio while Camren and Robin stepped out at the Entertainment Weekly party.

FYI: Camren is wearing Alice + Olivia at the party. Ben is wearing a Vince shirt, Early Morning Rebel Jeans, Armani loafers, a Mont Blanc watch, and Gallant & Beau socks at the panel.
