Read our privacy policy When Boston Celtics owner Wyc Grousbeck felt like his life could be the premise for a television sitcom, he knew just where to turn: His friend Tom Werner, a Red Sox owner and TV veteran who was behind megahits like “The Cosby Show,” “Roseanne,” and “That ’70s Show.” The result is “Extended Family,” which premieres on NBC on Saturday night starring Jon Cryer, Donald Faison and Abigail Spencer in a love triangle based on the real-life dynamic that developed between Grousbeck, his new wife and her ex-husband — a lifelong Celtics fan. “He looked at her like: ‘There’s a million guys in New England you could be dating,’” said Werner, who advised the three on developing the show and joined them as an executive producer. In the pilot, Jim hits Celtics owner Trey Turner up for tickets and his ex-wife Julia Mariano says: “Looks like we both met the man of our dreams.” But in real life there were more mixed emotions for Geyer, who grew up outside of Boston, went to Boston College and raised his kids as Boston sports fans while living in New York. “When they call you to do something like this, you’re excited because you think you might get some good tickets,” said O’Malley, who also worked with Werner — and NBA star LeBron James — on the series “Survivor’s Remorse.” “But then you realize: If I blow this, I might be persona non grata.’” Comedian Lenny Clarke brings his authentic Boston accent to his part as Jim’s father.
