The actress is currently starring in new movie `Hysteria` - which is set in the Victorian era and is about the invention of the sex toy - and she was bombarded with the pleasurable devices during shooting and so now gives the unwanted ones to her pals to enjoy.
She said: "By the time I finished the movie I`d been sent maybe 15 vibrators by different people in London with vibrator stores. It was a pleasant surprise.
"So I have this incredible collection, and I actually use like one or two of them. I lend them to my friends, and they-ll take them for six months at a time."
Maggie says she was drawn to `Hysteria` because she was keen to see how the vibrator was invented as well as being interested in "female sexuality".
Speaking at a press conference, she said: "I decided to do it because I was also interested in female sexuality, although that makes it so scientific. I don`t know many people who aren`t interested in female sexuality.
"I was curious about the invention of the vibrator. It`s unusual when you read a romantic comedy where you`re curious about what`s going to happen. Basically I`m always looking for freedom, for a way to be free in my work."
