Within a few weeks, Killen sent a rough draft of the script to his agent Marc Korman. "It was 1 or 2 o'clock in the morning, and I remember I was so freaked out by the script that I went upstairs to our guest bedroom where my wife was sick with the flu and I got into bed with her," recalled Korman.
