Jessica Chastain showed support for the SAG-AFTRA strike at the Venice International Film Festival on Friday.

Chastain, 46, attended the festival to promote Michel Franco's "Memory," which is debuting at the festival.

The actor is currently on strike alongside other members of SAG-AFTRA, the actor's union, over a variety of issues with production companies, including wages and protection against AI technology. The Writer's Guild is also on strike for similar reasons, and the dual stoppages have brought Hollywood to a screeching halt.

SAG-AFTRA's strike rules prevent actors from performing and promoting their projects, which includes attending film festivals. But "Memory" was granted an interim agreement with SAG-AFTRA, which allowed Chastain to promote the movie at the festival this year, as The Hollywood Reporter reported.

Although she was there to support the project, Chastain didn't let her attendance get in the way of her visible support for her union.

Chastain attended her first photo-call of the 2023 festival in a black "SAG-AFTRA on strike" T-shirt.

She paired the tee with a black miniskirt that featured button detailing. Black heels and oversized sunglasses completed the ensemble.

Chastain said she was "incredibly nervous" to go to the festival amid the strike but thought her attendance could send a message to studios at a press conference at the festival on Friday. Representatives for the actor shared a video from the press conference with Insider.

"I am here because SAG-AFTRA has been explicitly clear that the way to support the strike is to post on social media, walk the picket lines and to work and support interim agreement projects," she said.

"It's what our national board and our elected leadership has asked us to do," Chastain went on to say. "And when independent producers like the ones here sign these interim agreements, they are letting the world know and letting the AMPTP know that actors deserve a fair compensation, that AI protections should be implemented and there should be sharing of streaming revenue."

"So I hope being here today encourages other independent producers and encourages actors to show up and support our union members," she also said at the press conference. "And hopefully we'll see an end to this strike soon. And hopefully the AMPTP will go back to the table."

"Memory" is among a handful of films that have been granted interim agreements for the Venice Film Festival, and while much of Hollywood is visibly absent from this year's event a number of celebrities have still showed up in eye-catching fashion.
