NEW YORK (AP) — Famed conductor Gustavo Dudamel said Timothée Chalamet showed ignorance when the Oscar-nominated actor claimed “no one cares” about opera and ballet.

“Sadly sometimes it’s a little bit of ignorance but, look, that is why we have to open more spaces for people to connect with classical music,” Dudamel said Tuesday night at an event to announce the programming of his first season as the New York Philharmonic’s music director.

Dudamel spoke from the stage of Lincoln Center’s David Geffen to an audience that included donors, musicians, the orchestra board, community leaders and composers in addition to journalists. Dudamel’s remarks sparked loud applause.

During a conversation with fellow actor Matthew McConaugheyat a CNN and Variety town hall at the University of Texas at Austin’s Moody College of Communication in February, the 30-year-old Chalamet was asked by McConaughey about whether shortened audience attention spans have impacted studio decisions about the content of theatrical films, forcing more early action.

“I admire people, and I’ve done it myself, to go on a talk show and go: Hey, we’ve got to keep movie theaters alive. We got to keep this genre alive,’” Chalamet said. “And another part of me feels like if people want to see it, like ‘Barbie,’ like ‘Oppenheimer,’ they’re going to go see it and go out of their way to be loud and proud about it. And I don’t want to be working in ballet or opera or things where it’s like where it’s like, ‘Hey! Keep this thing alive,’ even though no one cares about this anymore. All respect to the ballet and opera people out there. I just lost 14 cents in viewership.”

Chalamet received his third Academy Award nomination, for “Marty Supreme.”His comments sparked an online backlash from arts organizations.

“Everybody has the right to say, but you have to do things with knowledge, with facts. I think we have to say to the young generation, the opposite,” Dudamel said. “It’s very funny. Cinema is a result of opera, of music, of all of these kind of things.”

Matías Tarnopolsky, the New York Philharmonic CEO, was seated next to Dudamel and issued a public offer to Chalamet.

“He can sit with me anytime,” Tarnopolsky said. “I’ll give him a free ticket and he’s invited to come and hear the New York Philharmonic.”

Dudamel, 45, is among the world’s most famous conductors. He is leaving the Los Angeles Philharmonic this summer after 17 seasons as music director to become the music director of the New York orchestra.

At one point, Dudamel feigned not knowing Chalamet, saying: “Which is the name of that?” before cutting off as the audience laughed.

“That way of thinking has to end,” he said. “Music is reborn all the time and it brings us the values of empathy through the beauty of what it is. So this is the reality of music. This is the real dimension of music and we need that more for our young people.”
