Filmmaker Pedro Almodovar earned a rousing applause at the Cannes Film Festival as he declared that "Europe must never be subjected to Trump" at a press conference for his new film Bitter Christmas.

The Spanish auteur, known for his internationally-acclaimed projects such as Pain and Glory, Volver and All About My Mother, was speaking on growing censorship concerns in the US and France, according to Variety.

He was asked about the controversy surrounding French network Canal+ whose CEO Maxime Saada has threatened to blacklist 600 artists for signing an open letter against main shareholder Vincent Bollore. Among the signatories of the letter are prominent names like Juliette Binoche and filmmaker Arthur Harari.

Almodovar, who wore "Free Palestine" pin at the red carpet of the movie gala, said artists should not back down despite threats.

“I don’t want to judge anyone, but I think artists have to speak out about the situation in which they live in contemporary society. It’s a moral duty,” the director said.

“Silence and fear is a symptom that things are going badly. It’s a serious sign democracy is crumbling. On the contrary, creators must speak out… the worst thing that could happen would be to remain silent or to be censored. We have a moral obligation to speak out," he added.

In an earlier interview with the Los Angeles Times, Almodovar also criticised the Oscars for being apolitical this year.

“You know, I’m not really blaming anyone in particular, but it was quite notable watching the Oscar telecast where there were not many protests against the war or against Trump.

“Maybe he wasn’t the only one, but the only real example I can remember came from a European, a friend of mine, Javier Bardem, who did directly say, 'Free Palestine’.”

“People are obviously very frightened,” the director continued and said he doesn't consider the US to be a "democracy right now".

"Some people say it’s maybe an imperfect democracy, but I really don’t think the US is a democracy right now. The heartbreaking and ironic thing is that democracy has given rise, through the proper, right voting mechanism, to this kind of totalitarian regime. And it’s both a paradox and it’s also incredibly sad," the 76-year-old said.

Asked whether he feared backlash for speaking out against Trump, Amodovar said he didn't have many fears.

"In a generalised Spanish sense, here we’re not afraid to call things for what they are. We have a government that has called Gaza a genocide and the Spanish people in general are not afraid to call these wars out for what they are,” he said.

Cannes has been a regular platform for the director whose new film earned a 6.5-minute standing ovation.

He previously won the best director prize at Cannes for his 1999 film All About My Mother and best screenplay for Volver in 2006.

Bardem, who has often spoken out against Israel, and Almodovar have collaborated on a number of films including High Flesh, Women on the Verge of a Nervous Breakdown and High Heels.

He has also worked with actor Penelope Cruz, who is married to Bardem, in films such as Volver, Parallel Mothers, Broken Embraces, Pain and Glory and High Flesh.
