Stephen Colbert spent a decade courting Hollywood royalty behind his "Late Show" desk, but now he's getting the star treatment.Several A-listers, from Oscar-winning actress Jane Fonda and "Star Wars" icon Mark Hamill to fellow late-night host Jimmy Fallon, paid tribute to the Emmy-winning television host online as he concluded his CBS talk show on May 21, after 11 seasons.Fonda, 88, was joined by other outspoken celebrities in a video for the Committee for the First Amendment, a collective of artists advocating for free speech. The "Coming Home" actress, who spearheaded the group's revival in 2025, praised Colbert for his endearing mix of humor and conviction."He made us laugh, and he never flinched," Fonda said in the May 21 video.Colbert revealed last July that CBS canceled his talk show after a decade on the air. The "Late Show" franchise, which debuted in 1993, will also be retired along with Colbert's cancellation (Byron Allen's "Comics Unleashed" is slated to fill the time slot).The shocking ouster came amid increasing political scrutiny of Colbert, who'd voiced criticism of CBS' former parent company, Paramount Global, and its settlement deal with President Donald Trump in a case involving "60 Minutes."In a statement at the time, Paramount executives called the move "purely a financial decision against a challenging backdrop in late night," adding that Colbert's removal was "not related in any way to the show's performance, content or other matters happening at Paramount."Here's what other stars are saying about Colbert and the impact of his show.Mark Ruffalo, Sally Field, more stars honor Stephen Colbert amid show cancellationAside from Fonda, the Committee for the First Amendment's video on Colbert's cancellation featured several Hollywood luminaries, including Oscar-nominated actor and Trump critic Mark Ruffalo."I'm going to miss him, and I'm disturbed by what it means that he'll be gone," Ruffalo, 58, said.
