Sean Astin says he is happy to be at the head of the actors union at a vital moment. The 54-year-old actor from "The Lord of the Rings" films is the new president of the The actors union SAG-AFTRA. He'll be leading the group as it begins contract talks with studios that last time led to a long strike. Astin says the union's negotiators can't give up any of the ground they earned during the 2023 strike, including higher wages and artificial intelligence protections. Astin says he intends to represent every member, from the biggest movie star to the most anonymous puppeteer.
