Truly, the only times I would really break were in the scenes with Vince.
They were both so invested and they both did so much research with each other to learn about movements – Kathryn learned the Butcher walk, Vince learned the hair flip for Millie.
It was actually relatively easy not to laugh or break because you were constantly on your toes with both of them.
They were both so committed and I mean that legitimately.
