Actress Judy Greer, the consummate sidekick, best friend, or both in countless films, has been approached by so many people who can't quite figure out where they've seen her before that she wrote a book about it, I Don't Know What You Know Me From: Confessions of a Co-Star (Doubleday; out April 8). We asked her about being almost-famous.
DETAILS: Do that many people really come up to you without knowing who you are?
JUDY GREER: Just last night I gave a copy of my book to a girlfriend at dinner, and a woman came up to our table. She goes, "I have to say hi to you, I have to say hi to you." I said, "Okay, hi!" And she said, "I don't even know who you are!"
DETAILS: What's your most awkward story about being mistaken for someone else?
JUDY GREER: One time, a guy came up to me in a store crying, and he told me my performance in Magnolia changed his life. Tears were rolling down his face! And I just said thank you. He thought I was Melora Walters—and I'm not her, but I didn't want to ruin his moment, like, "Wrong girl, buddy!"
DETAILS: Have you ever had to reintroduce yourself to an A-lister you'd been in a movie with?
JUDY GREER: I ran into [my Wedding Planner costar] Jennifer Lopez a few years ago, and she didn't know who I was. She gave me the "Hi...?" smile. To be fair, how many people does that woman meet in a day? I'm sure she's still really upset about it.
