David Schwimmer has slammed Hollywood stars for refusing to speak out against anti-Semitism.

The 58-year-old actor spoke at the Anti-Defamation League's Never is Now conference in New York City last week, where he hit out at his "heroes" who have remained silent amid the current conflict in the Middle East.

According to DailyMail.com, he said: "Plenty of people I respect, even some of my heroes in entertainment, music and sports, have chosen to keep a low profile and sit this one out, including some whose careers have been made by leaning into their Jewish identity, and others who have won acclaim for playing Jews onscreen.

'Some of them are doing a lot behind the scenes, privately and in their own way, but so many have chosen not to say anything publicly at all.

'And if I can say something directly to them: I really wish you would.

"I wish you would stand up. I wish you would speak out, because your voice would be so meaningful to your fans who love you, to your community members who need you, to folks who can use just a little solidarity right now.

"No one's asking you to solve the conflict of the Middle East. Just say that you stand with your Jewish friends, colleagues, and neighbours against hatred and what's happening on our college campuses and in our schools and to Jewish-owned businesses is totally unacceptable."

Gal Gadot, 39, also took to the stage, where she called for the release of Israeli hostages in Gaza.

She said: "With every hostage release we hear new testimonies of the horrors they've been through. Every minute for them is hell. Their lives are in danger and we need them home.

"None of us can ignore the explosion of Jew hatred around the world anymore. We have had enough of Jew hatred we will confront anti-Semitism. We will call it out, but we will never let it, not only, defeat us but define us because our love is stronger than their hate."
