The Oscar winner decided to have a little fun with her character, Grace Trevelyan Grey, in between takes and posted pictures of on-set sex toys on social media.

"I was a little bit fascinated with the toys, so I had sent out a tweet... that said something like: 'Dear Christian, thank you for the lovely sweater clasps, but the picture was of nipple clamps," she tells Access Hollywood Live.

"They (producers) told my publicist that I had to delete it... They were like, 'Marcia, you really can't do that!' I was like, 'OK, I'll stop doing it', but it was so hard no to."
