Spike Lee recently sat down with fellow film directors Alfonso Cuarón, Karyn Kusama, Josie Rourke, Yorgos Lanthimos and Ryan Coogler in Los Angeles to discuss their critically acclaimed movies.

The six filmmakers were interviewed by entertainment journalists Amy Kaufman and Mark Olsen for the Los Angeles Times’ The Envelope roundtables presented by Spectrum News 1.

Lee drew laughs from the group when he complained about the growing number of people who watch movies on mobile phones.  

The BlacKkKlansman director, who teaches film classes at New York University, said he hears about it from his students all the time.

"The first of every semester, I have a list of films. I ask my students to raise your hand if you've seen this film," Lee explained. "They say 'yes I saw it professor Lee, but I saw it on my iPhone.'"

Lee, 61, said he's bothered by the practice, and often responds to his students with "Oh my God!"

The director, whose career took off after the release of his 1986 film She's Gotta Have It, believes movies should be seen in theaters, especially classics like Doctor Zhivago and The Bridge on the River Kwai.

"It hurts my heart," he said about the practice of watching movies on tiny screens.

Roma director Cuarón, 57, agreed and asked, "Why on the iPhone?"

Black Panther filmmaker Coogler, 32, suggested the two sounded a little old fashioned.

"You've got to see it from their perspective," Coogler said about young people who live on their smartphones.

Lee admitted he's old school and jokingly referred to himself as a "dinosaur."
