Successful New York playwright Jon Robin Baitz, the creator of my favorite show "Brothers & Sisters." did an intrerview with AfterElton.com about being phased out the show early this season and leaving Los Angeles. I've excerpted the parts about the gay character of Kevin Walker but encourage you to read the entire article. There is a link at the bottom:

On the character of Kevin Walker: "It couldn’t have succeeded with an actor who had any reluctance whatsoever. Because in Matthew Rhys there’s this fabulous combination of openness, availability, intellect, humility, arrogance, self-deprecation, introspection. He has underpinnings of Hamlet to him. And underpinnings of Monty Python too. And occasionally the out of control qualities of Lenny Bruce. And I think he’s wildly educated about the self — his self. And so it was very useful. We cast it very well. And I think that went right. Also there might be something sort of Welsh about him, he’s such a convivial man, that the notion of being embarrassed by [the character’s] sexuality couldn’t have been further from the truth.

On the actors cast as Kevin's love interests: "You know Jason Lewis is...an evolved, thinking, sensitive man. And Luke MacFarlane is a brave, bold, athletic, curious actor who has a lot of training. You know, he came out of Julliard, came out of the theater. So those two in particular were entirely comfortable with the entire business. I’m telling you, there’s a list of actors that we’d go out to to play guest star boyfriends — and it would come back: doesn’t want to play gay, doesn’t want to play gay. I’m not going to name them."
