For example, when Bill arrives for his birthday and before he even says goodbye to Margo he is talking to Eve. This sparks something in Margo, where we can see that she is jealous. As a viewer I could see his insecurity in this moment. As an actress in her 40s, I think Margo's biggest fear as she got older was losing character roles in her 20s to actresses in their 20s, like Eve. This was made very clear when she told Lloyde that she didn't want to play Cora, a character in her twenties. She begins to explain that she is in her forties and doesn't need these roles since she will be married. He explains that he now has a life to live. Margo expressed her concerns about aging in many ways. He was afraid of losing Bill to younger women, afraid of losing parts to younger actresses. I think in the end people didn't take their fears seriously. I think the only time anyone could have taken her seriously was Bill during the audition, after Margo found out Eve was his replacement. He kind of realized that these insecurities of Margo's were ruining what they had, and that's when he gave her an ultimatum. At this point his fears drove him away. I think the character of Bette Davis showed every actress' greatest fear. The fear of not being who your character is, of no longer being twenty, of having to be forty playing a twenty-year-old
