He is donating his salary from the upcoming Woody Allen movie "A Rainy Day in New York" to the anti-harassment Times Up fund; RAINN, which supports victims of sexual violence; and the LGBT Center in New York City.
In an Instagram post, Chalamet said, "I am learning that a good role isn't the only criteria for accepting a job" and lauded the "powerful movement intent on ending injustice, inequality, and above all, silence."
His co-star on "A Rainy Day in New York," Rebecca Hall, also recently announced she would donate her salary to Times Up. Last year, their castmate Griffin Newman donated his to RAINN.
Chalamet joins a group of actors, including Greta Gerwig and Mira Sorvino, distancing themselves from Allen after his daughter, Dylan Farrow, wrote an op-ed in the Los Angeles Times criticizing the industry for continuing to work with the director. He was accused of molesting Farrow when she was a child, a claim Allen has denied.
