Charlie Sheen said his father -- who played a therapist in the show's ninth episode -- could return as an official cast member if "Anger Management" is renewed, the Los Angeles Times reported.
"He was great, he was awesome," Charlie Sheen said of working with his father on the series. "He brings a whole different energy."
FX President John Landgraf said at the FX's Television Critics' Association panel on Saturday that he was pleased with the series' ratings and that it had exceeded the audience necessary for a renewal.
When asked about how his life is different now compared to his public breakdown after leaving "Two and a Half Men," Charlie Sheen was quiet and subdued, the Times said.
"I don't know -- I learned a lot," he said. "Stick to what you know. Don't go on the road to 21 cities with no act."
