They want to portray the Cupid as a humorously loving character who "greets everyone with enormous bear hugs that almost break their ribs." He is required to be "overflowing with love and positivity to an almost humorous and narcotic degree". To provide more insight of what kind of person they want, the casting directors specifically wanted someone like Will Ferrell in "Elf".
Cupid will be a guest star in the episode called "My Bloody Valentine". Beside Cupid, the episode also requires an actor for Famine. He is one of the Four Horsemen of the Apocalypse, who is withered, weak, raspy. This character is a creepy and destructive old man filled with a voracious hunger.
"Supernatural" is currently on Winter hiatus and will be back for a new episode called "Sam, Interrupted" on January 21.
