Dillahunt took inspiration from Andrew Cunanan, the man who killed Gianni Versace, when he recalled the brutality in which Cunanan murdered a man just for his car. Dillahunt recalls how an FBI profiler noted that this type of rage is typically directed toward someone the perpetrator knows, yet Cunanan managed to pull some element from his own life and place it on this random person who attempted to stand his ground against the would-be carjacker. To Dillahunt, that was how he wanted to approach Krug. To him, Mari actually shows that she is not afraid of Krug, which causes him to go "crazy". That being said, the actor felt like the scene where his character rapes Mari was one of the hardest things emotionally to film.[7] He notes that part of him was happy that Sara Paxton was cast as Mari, because they had worked together in the past, so they knew each other. On the other hand, he felt uncomfortable acting out such a scene with a person he considered to be a friend.[8] Paxton echoed his sentiments to Craven, who stated the actress expressed to him a greater feeling of trust that the person who would have to do these "horrible" things to her was someone she knew, and as a result made them at least partially more bearable to act.[4]
