Production

Steve Franks, creator of the series, returned for the fourth season as showrunner. The theme song, "I Know, You Know" by The Friendly Indians, continued to be used, though it was edited twice: in "Bollywood Homicide", the song was given a Bollywood theme with the lyrics sung in Hindi, while Boyz II Men performed an a cappella version for "High Top Fade Out".

Mel Damski returned to direct four episodes, while Stephen Surjik returned for three and Steve Franks directed two. Returning to direct one episode each were John Badham, Jay Chandrasekhar, Michael McMurray, James Roday and Matt Shakman. Andrew Bernstein and Tawnia McKiernan each joined the show to direct one episode.

Steve Franks wrote five episodes, while Andy Berman wrote four and Kell Cahoon, Saladin K. Patterson and James Roday wrote three. Returning for two episodes each were writers Tim Meltreger and Anupam Nigam. Bill Callahan and Todd Harthan joined the writing team, with Callahan writing three episodes, and Harthan writing one.
