Here is where she is asked about the incident in a New York Times interview.
That demand for straightforward professionalism (and dislike of egos) possibly fed what, for the nontheatergoing public, is the most notorious episode of her career. In 2006 she starred with Alec Baldwin in a Roundabout Theater Company production of Joe Orton’s black comedy “Entertaining Mr. Sloane.” She got the tabloid treatment when a personal e-mail message complaining about Mr. Baldwin’s backstage behavior — including punching his fist into a wall — found its way into the press. Ms Maxwell departed the show with a month left in the run. While her career has continued to thrive, the incident has had a long shelf life. In a profile of Mr. Baldwin in a recent issue of The New Yorker, he and Scott Ellis, who directed “Entertaining Mr. Sloane” and has worked on Mr. Baldwin’s sitcom “30 Rock,” offered fresh disparagement of Ms. Maxwell.
Asked whether she would handle the situation differently if given the chance, she fell silent. “It’s like opening a huge can of worms each time,” she finally said. “I don’t have the finances or the arsenal of publicists and minions to tell my side of the story. I just have to know that I did the right thing.” She added with a sigh: “The air that I’m breathing in talking about it now seems to be a waste for me. I don’t think they’re worth the time.”
