Actress Julia Stiles lost her temper recently - when she caught a stranger trying to take a photograph of her in a swimming pool changing room.
The 26-year-old is determined to protect her anonymity and worries about unsuitable pictures of her ending up online.
She says, "I went swimming at the YMCA and somebody in the locker room tried to take a picture of me with a cellphone.
"I lost it. I was like, 'Are you kidding me?' Then I felt bad because she thought I was being a bitch."
