The actress, who played Peggy Olsen on "Mad Men", said she has been subjected to sexism a lot of times in Hollywood, reported Female First.
"Have I experienced sexism like Peggy did in the 1960s? Of course not. But have there been times when I haven't made as much as a man? I'm sure. And it's a factual thing, not a matter of opinion. That's sexist."
The 33-year-old actress is currently working on a potential TV adaptation of a book, which she plans to produce herself, and has been shocked that studios have passed on the project because it has a female protagonist.
"It's inane and archaic and I can't believe people are still getting away with saying that.
