Under pressure from French film entities, the festival announced last week that it had changed its rules to require future competition films to have a French theatrical release.
At a news conference here on Wednesday, Pedro Almodóvar, the Cannes jury president, read a manifesto defending theatrical screenings and said it would be a paradox to give the Palme d’Or to a film that wouldn’t be seen on screens. “The size of the screen should not be smaller than the chair you’re sitting on,” Mr. Almodóvar said.
“Why would we want to hold back a movie for an enormous number of people to enjoy throughout the entire country that a few hundred, maybe a few thousand people could see the film in Paris?” Mr. Sarandos said. “It seemed to me like the right thing to do was to give the people, our subscribers, who pay to make these movies, access to them immediately all over the world,” he added.
Asked if the festival organizers were aware that Netflix wasn’t seeking a wide theatrical release in France, Mr. Sarandos said, “They were fully aware of our release strategy.”
Not everyone here was critical of Netflix. A Cannes juror, Will Smith, defended it at the news conference with Mr. Almodóvar. “In my home it’s done nothing but broaden my children’s cinematic global comprehension,” he said. Mr. Smith stars in “Bright,” a thriller that will debut on Netflix this year.
Another actor said that he was drawn to a Netflix project because of the company’s large viewership. At a news conference for “Okja” here on Friday, Jake Gyllenhaal, a co-star, said he had wanted the movie — with its strong environmentalist message, and critique of capitalism and genetically modified food — to connect with a wide audience.
“The platform of a film, how far it can reach, how many people it can get to reach a message, is extraordinarily important,” Mr. Gyllenhaal said. “It’s a true a blessing when any art can reach one person if not hundreds of thousands if not millions of people.”
The other Netflix-produced film at the festival is “The Meyerowitz Stories,” directed by Noah Baumbach.
Netflix has local content in 23 languages and is currently filming in 19 countries. This year it will distribute 50 feature films, not including documentaries. Mr. Sarandos wouldn’t reveal how many subscribers Netflix has in France or elsewhere, saying only that half of its 100 million subscribers are in the United States and the rest are in 189 other countries. “It’s a very competitive marketplace,” he said, declining to break down the numbers any further.
He said that about 30 percent of the content Netflix subscribers watch in any country on an average day was local, although that can vary, and that Netflix had invested 1.75 billion euros (about $1.9 billion) in European content since 2012.
It was at a previous Cannes Film Festival that Mr. Sarandos made a connection with Thierry Frémaux, the festival’s director. They went to a screening of a newly restored “The Lady From Shanghai” by Orson Welles. “That’s when we bonded and he saw I really do love movies,” Mr. Sarandos said.
Netflix is financing the completion of “The Other Side of the Wind,” Welles’s unfinished film. Mr. Sarandos hopes it might debut at Cannes. “I’ve talked to Thierry many times and said this is where we’d like to show it,” he said.
