David Krumholtz is finalizing a deal to play the lead opposite Michael Urie in CBS’ half-hour pilot Partners. The multicamera comedy, from Will & Grace creators Max Mutchnick and David Kohan, centers on lifelong friends and business partners — architects  Charlie (Krumholtz), who is straight, and Louis (Urie), who is gay. Sophia Bush co-stars as Charlie’s fiance; Brandon Routh as Louis’ partner. This marks Krumholtz’s return to comedy after a string of drama series gigs. The Numbers alum, repped by Gersh and The Collective, most recently co-starred on NBC’s The Playboy Club earlier this season.
