He was praised by his former
Supernatural (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.
