He was praised by his former Sobrenatural (2005) co-star, Jensen Ackles, at the LA Supernatural Convention in 2011. Ackles says that during the torture scene of Christopher's character "Alastair", Ackles was thinking "Wow, I'm totally being out-acted here", after that Ackles turns to the audience and asks them "I mean, wasn't he good?" The audience replies with massive applause.
What I find interesting about a character like The Swede (in Infierno sobre ruedas (2011)) is that the menace is there because we assume he is capable of anything. Do we actually see him do anything? Rarely. But the more humane I play these characters, the more kind, the more generous, the more menacing they seem.
