The 40-year-old actress took to Twitter to express her displeasure.
"I'll just Netflix and chill. Or some HBO greatness. Or anything by Ryan Murphy. There's so many incredible options that don't include CBS," Chastain tweeted.
Her tweet comes in response to news that came out of this week's Television Critics Association panel, when CBS senior executive vice president Thom Sherman was asked about the network's continued lack of diversity in its programming.
"We had six pilots with female leads and the way things turned out those pilots were not deemed to be as good as the pilots that were picked up," he had said.
