Last season, USA Network’s flagship series Royal Pains introduced Hank Lawson (Mark Feuerstein) and Evan R. Lawson’s (Paulo Costanzo) dad Eddie Lawson, played by Henry Winkler. Now the upcoming third season will go down another generation, with veteran Ed Asner tapped for a 2-episode arc as Ted Roth, Hank and Evan’s grandfather and Eddie’s dad. Asner, repped by Greene & Assoc. & manager Perry Zimel, recently starred on CMT's first sitcom Working Class. He is now touring the country with his one-man show FDR and will next be seen in the HBO movie Too Big to Fail.
