Secrets from Set: This week, Dominic Sherwood and Katherine McNamara took us through that intense rooftop fight scene between Jace and Clary. The power of green screens and safety wires allowed for Sherwood to dangle his scene partner over that ledge and then drop her onto the car below, but the real hilarity came in when they were staging the aftermath of Clary’s fall.

“One of the morbidly humorous things that we had to do was they had the car on set, and they said, ‘Hey, Kat, here’s some old pictures of people that have fallen from great heights and died. Can you, uh, contort yourself in any of these ways so we can, you know, dent the car properly?” Kat McNamara reveals.
