In addition to thinking about her own marriages, Janet was able to draw on another real-life experience for her role. In the movie, Janet's character learns that one of her best friends has a cheating husband, but she decides not to tell. When faced with the same circumstance in real life, Janet made the same choice.
"I didn't say a thing, and she was very upset at me for it," Janet says. "But I felt it wasn't my responsibility, my job to. I would want him to man up and come to her. And because of [my decision], we are no longer friends."
Even after portraying a similar situation onscreen, Janet says she would make the same decision again. "If it were happening to me, I would want [him] to come to me and let me know," she says.
