(CNN) Natalie Portman's subtle tribute to female filmmakers at the 2020 Oscars did not go over well with Rose McGowan, who called Portman's show of support -- wearing a cape with the names of women who directed films in the past year -- "an actress acting the part of someone who cares."

McGowan took to Facebook Tuesday with her thoughts, writing, "I find Portman's type of activism deeply offensive to those of us who actually do the work. I'm not writing this out of bitterness, I am writing out of disgust. I just want her and other actresses to walk the walk."

She described Portman's effort as the "kind of protest that gets rave reviews from the mainstream media for its bravery."

Portman responded to McGowan's post in a statement issued Wednesday.

"I agree with Ms. McGowan that it is inaccurate to call me 'brave' for wearing a garment with women's names on it," Portman said in a statement to CNN. "Brave is a term I more strongly associate with actions like those of the women who have been testifying against Harvey Weinstein the last few weeks, under incredible pressure."
