Alan Rosenberg didn’t go into acting just to be an entertainer. “There’s a potential for a deeper experience,” says the co-star of the CBS series “The Guardian.” What speaks to him about his character, Alvin Masterson, the chief of a children’s legal advocacy service, is that the role is grounded in realism. “The show deals with issues that matter to me — children’s issues, and how the system makes it difficult to care for them. The characters are all flawed. They all make big mistakes, but they all do great things. Coming out of the ’60s, that was really important to me.”

So much so that Rosenberg, who has also appeared on “L.A. Law,” “Chicago Hope” and “Cybill,” says he’s considering the idea of running for political office. “Nobody’s talking about the things I’d like to see talked about. You’ve got to step up and be counted.”

Rosenberg will admit that his original reason for getting into acting was motivated by a desire to “change the world.”

“The first theater I did was guerrilla theater, opposing the war in Vietnam.”

He was very much a political activist during that war, alongside his brother Mark Rosenberg, who became president of Warner Bros. Pictures and a producer who worked with Sydney Pollack. “He was my hero,” says Rosenberg.

The actor’s familial pride certainly extends to his cousin, musician Donald Fagan, and his wife, Marg Helgenberger, star of “CSI.” When they first met, Rosenberg says he had lost his ambition and spark. “She inspired me to dream again.”
