The 47-year-old actress has revealed she was originally offered half that her co-star was for the lead role in the reboot of the popular show.

She said: "Especially in this climate of women talking about the reality of [unequal pay] in this business, I think it's important that it gets heard and voiced.

"It was shocking to me, given all the work that I had done in the past to get us to be paid fairly. I worked really hard toward that and finally got somewhere with it."

And Gillian admits she has a "very short tolerance" for being treated differently simply because she is a woman.

She added to the Daily Beast: "I have such a knee-jerk reaction to that stuff, a very short tolerance for that s**t. I don't know how long it lasted or if it changed because I eventually said, 'F**k no! No!' I don't remember somebody saying, 'Okay, now you get to walk alongside him.' But I imagine it had more to do with my intolerance and spunk than it being an allowance that was made.

"People have said to me, 'I can't believe that happened, how did you feel about it, that is insane.' And my response always was, 'That was then, this is now.' And then it happened again! I don't even know what to say about it."
