Human Target would premiere mid-season. The show was filmed in Vancouver, British Columbia. Human Target was renewed for a second season in May 2010. Matt Miller took over as showrunner from Jon E. Steinberg who remained part of the production team as an executive producer. Warner Bros. had contacted Miller to take a look at the first season and give his opinions on what changes he would make to the show. The show was officially canceled on May 10, 2011. Casting In the original concept, Jackie Earle Haley's character Guerrero was intended to have a one-time appearance in the pilot episode, and every episode thereafter would feature a different character assisting Chance and Winston. However, the producers liked Haley's performance and his character, and invited the actor to be a regular on the series. Music Composer Bear McCreary scored the music for the first season, for which he received an Emmy Award nomination for Outstanding Main Title Theme Music. He wanted to create a modern classic-adventure score", and a heroic but still fun and iconic theme for Chance. Chance's theme later became the opening theme for the first season. McCreary wrote around 30 minutes of full orchestral music for 11 weeks in a row, which was performed by an average of 60 musicians. The score for the final episode of the season, "Christopher Chance", was performed by a total of 94 musicians, making it the largest live orchestra ever assembled for a television series. McCreary was not asked back for the second season as they could no longer afford a weekly 40-person orchestra. Chuck composer Tim Jones took over the role.
