After a source reportedly told the New York Post that Abbott “didn’t like the direction things are going in,” his rep told The Hollywood Reporter that he was simply too busy for the HBO series.
“[Chris] is grateful for the experience of collaborating with Lena, Judd [Apatow], and the entire ‘Girls’ cast and crew, but right now he’s working on numerous other projects and has decided not to return to the show.”
“The world that Lena wrote was very real, especially in New York,” he said. “But it wasn’t as relatable for me on a personal level. It’s not that I only like to play roles I know to a T, but there’s something satisfying about playing parts where you really relate to the characters.”
