"Brothers & Sisters" showrunner David Marshall Grant (CAA, Untitled, Jackoway Tyerman) is developing a comedy for HBO, adapting the Israeli series "Ran Quartet" for CBS and executive producing the drama "Blink" for The CW.

David Marshall Grant ("Brothers and Sisters") and Sarah Condon ("Bored to Death") will executive produce the project.

HBO is adding San Francisco to its itinerary.

Hours after picking up a project about siblings in New Jersey, the premium cable network said Friday that it has ordered to pilot a comedy about three gay friends living in San Francisco.

The untitled project hails from Brothers and Sisters' David Marshall Grant and Bored to Death's Sarah Condon and revolves around the thirtysomething trio also grappling with the complexities of life and the modern gay experience. Michael Lannan (Remember Me) penned the script, which Grant supervised. Andrew Haigh will helm the pilot, which is based on Lannan's feature script Lorimer.

The untitled comedy joins People in New Jersey, from Bruce Eric Kaplan, Lorne Michaels and Jason Reitman, and Stephen Merchant comedy Hello Ladies, which was picked up to series, at the network as it looks to bolster its comedy coffers which already include Enlightened, Girls and Veep, among others.

The comedy marks Lannan's first major writing credit. His résumé also includes writing, directing and producing the 2009 short Lorimer, Sons of Anarchy, serving as an assistant producer on Rubicon and an AD on Nurse Jackie.

Grant most recently served as a writing exec producer on NBC's Smash and penned an episode of ABC's freshman musical drama Nashville. He's repped by CAA, Untitled Entertainment and Jackoway Tyerman.
