Russell Tovey has joined the cast of HBO's upcoming gay-themed series Looking.

According to The Hollywood Reporter, Tovey will play Kevin, an accomplished video game wunderkind, who works closely with Patrick, played by Jonathan Groff (Glee, Boss).

In additional to Groff, the show stars Murray Bartlett (Guiding Light) and newcomer Frankie J. Alvarez (Smash) as a trio of friends grappling with gay life in San Francisco, America's most gay-friendly city.

The 8-episode series' pilot was directed by Andrew Haigh, whose brilliant film Weekend about a 48-hour relationship between two men has collected numerous film festival prizes.

It is the first major U.S. role for 31-year-old openly gay Tovey, who is best know for his role as werewolf George Sands in the BBC supernatural drama Being Human, and his first major role playing gay.

“Every character I play is straight, which is unique, my agent says, because it's not really been done before that someone who is completely out is able to play straight roles,” Tovey earlier told the Independent. “So for me to play gay it has to be something special, because it might actually be more of a risk. So I'm waiting for that role – I want it to be something that moves things forward.”
