"I felt honored the moment she signed on to do the film," Wiig, 37, tells Collider. "She was a very maternal, nurturing spirit. She was also game for anything. There were times when she was saying things and I would just start laughing. I was like, 'Oh, my god, I'm making Jill Clayburgh talk about motor-boating,' which didn't end up in the movie. She was amazing."
According to producer Judd Apatow, 43, they wanted to honor Clayburgh's legacy without making her appear crass on film.
"We took some dirty Jill Clayburgh jokes out because I just thought, 'That can't be the last thing she ever says in a film,'" he explains. "We did debate it. We were like, 'That's funny, but that would be questionable.'"
"She was the nicest woman," Apatow continues. "We're all so influenced by her work and her acting style. We really appreciate that real, naturalistic acting style. She was just a great woman. None of us knew she was sick. She was just awesome, every day."
