At the Cannes film festival American actress appeared in a blue dress with a deep neckline accentuating her ample bosom.
Mexican actress Selma Hayek says male stars' huge salaries for films is making their female co-stars in the shade.
"I will be hated for saying this", Hayek joked.
Hayek said inflated fees demanded by some leading actors, whom she did not name, could mean there was less money left for their female co-stars.
According to Hayek, however, it is not just women who have suffered as a effect of powerful men abusing their positions.
In a discussion with the Radio Times, Cumberbatch called on male actors to step up to the plate and refuse to take more money than what their female counterparts were being paid, even going as far as to reject work outright.
"We couldn't have done it without a few good men, like my husband", she said, adding that it was "so sexy and unnerving when he comes up with ideas that I should have".More news: Indian Pavilion Inaugurated at Cannes Film Festival 2018
The 51-year-old actress came forward last year as one of over 50 women to place misconduct allegations against the disgraced producer, and her claims were met with a denial from Weinstein himself.
In a lengthy statement, Weinstein apologised for his "boorish behavior" following a screening of "Frida" but claimed he never fought with Hayek on set and didn't recall some of her allegations. Hayek added. "So, he went back, attacking the two women of color ... if he could discredit us, which would be easier for the audience, the readers to not believe us, he could then maybe discredit the rest".
Hayek says that the Me Too movement can be empowering for men as well.
"When you start seeing people standing up for their rights and being heard, it becomes contagious", she said.
While the two incidents may have appeared to be isolated, at the Women In Motion panel at Cannes on Sunday, May 13, Hayek argued that Weinstein had been especially dismissive of allegations made by herself and Nyong'o because they are both women of color.
"I think it's an invitation for us to think differently and to act differently", she said.
