Michael Lannan created the half-hour series, which stars Groff (Spring Awakening, "Glee," "The Normal Heart"), Frankie J. Alvarez and Murray Bartlett as three young gay men living in San Francisco. The cast also features Russell Tovey and Scott Bakula.
"Looking" will air at 10:30 PM ET.
According to HBO, "'Looking' offers up the unfiltered experiences of three close friends living - and loving - in modern-day San Francisco. Friendship may bind them, but each is at a markedly different point in his journey: Patrick (Groff) is the 29-year-old video game designer getting back into the dating world in the wake of his ex's engagement; aspiring artist Agustín (Alvarez), 31, is questioning the idea of monogamy amid a move to domesticate with his boyfriend; and the group's oldest member - longtime waiter Dom (Bartlett), 39 - is facing middle age with romantic and professional dreams still unfulfilled.
"The trio's stories intertwine and unspool dramatically as they search for happiness and intimacy in an age of unparalleled choices - and rights - for gay men. Also important to the 'Looking' mix is the progressive, unpredictable, sexually open culture of the Bay Area, with real San Francisco locations serving as a backdrop for the group's lives. Rounding out the 'Looking' world are a bevy of dynamic gay men including Kevin (Tovey), Lynn (Bakula), and Richie (Castillo), as well as a wide-range of supporting characters like Dom's roommate Doris (Lauren Weedman), Agustín's boyfriend Frank (O.T. Fagbenle), and Patrick's co-worker Owen (Andrew Law)."
Andrew Haigh, who directs the series, produces along with Sarah Condon and David Marshall Grant.
