NEW YORK — Hundreds of Hollywood and Broadway stars - including Robert De Niro, Ben Affleck, Jennifer Aniston, Selena Gomez, Lin-Manuel Miranda, Tom Hanks and Meryl Streep - are urging Americans “fight to defend and preserve our constitutionally protected rights” in the wake of Jimmy Kimmel’s suspension.

More than 430 movie, TV and stage stars as well as comedians, directors and writers added their names to an open letter Monday from the American Civil Liberties Union that argues it is “a dark moment for freedom of speech in our nation.”

The move comes less than a week after ABC suspended Kimmel’s late-night talk show following comments he made about the assassination of conservative activist Charlie Kirk. After a group of ABC-affiliated stations said they wouldn’t air “Jimmy Kimmel Live!” The Walt Disney Co. pulled the show Wednesday just before air, prompting a firestorm of debate over free speech.

“Regardless of our political affiliation, or whether we engage in politics or not, we all love our country,” the letter says. “We also share the belief that our voices should never be silenced by those in power - because if it happens to one of us, it happens to all of us.”

The list of signatories includes newly crowned Emmy-winner Noah Wyle, Oscar-nominated Florence Pugh, comedian David Cross, Tony-winner Kelli O’Hara and veteran actor Molly Ringwald. Pedro Pascal, Billy Crystal, Nathan Lane, Kerry Washington and Kevin Bacon also signed.

“This is the moment to defend free speech across our nation. We encourage all Americans to join us, along with the ACLU, in the fight to defend and preserve our constitutionally protected rights,” the letter concludes.
