Image Credit: Matt Carr/Getty Images; David M. Russell/CBSThe Good Wife has tapped Dallas Roberts to play the potentially recurring role of Alicia’s (Julianna Margulies) never-before-seen gay brother, sources confirm to me exclusively.

Exec producer Robert King, however, says don’t expect a whole lot of drama to arise from his sexual orientation. “We just thought [it would be interesting] if it didn’t matter.

“Everybody around them thinks it’s an issue between them, but there’s no issue,” he reiterates. “We kind of like that it voids expectations of what will happen between them.”

So what will happen when Owen, a University of Oregon mathematics teacher, passes through Chicago as a visiting professor? “What this character allows us to do is access more of Alicia’s back story,” King explains. “She was always the good older sister, he was always the younger, more free-spirited brother.”

“And,” he adds, “we’ll see a little bit about what their parents were about.” (Additional reporting by Tanner Stransky)
