50/50, which centres on a young man named Adam (Gordon-Levitt) as he copes with a cancer diagnosis and his subsequent illness, sees Kendrick as therapist-in-training Katherine, who is also a love interest for Adam.
"The studio wanted to see us kiss at the end, actually. We were thinking about just trying it as an option. Joe very wisely stood up and said, 'If we give it to them as an option, they will use it'," Kendrick recalled in an interview with MTV News.
"So we just decided not to do it, because it really just didn't feel right. And I was relieved, because I had known Joe for too long at that point. It's too weird once you think of someone as a friend to be like, 'OK, I guess we make out now?'"
However, Gordon-Levitt joked that he was disappointed by the omission, adding: "It's a travesty. It's a horrible injustice, and I'm writing a letter."
Gordon Levitt has said that he was convinced he was going to die after wrapping production on 50/50.
Co-star Seth Rogen recently insisted the film represents a cancer story that is true to life.
