Director Luca Guadagnino and stars Armie Hammer, Timothée Chalamet, and Michael Stuhlbarg discussed their gay love story “Call Me by Your Name,” and how art can be an agent of change.

“The shooting of the actual scene of the first kiss — it felt as organic and special and great as every other shot that we did on this movie,” Hammer said, adding that he hopes we’ve evolved sociologically since “Brokeback Mountain” was released to controversy in 2005 to see “the truth that’s present in every moment of desire.”

The foursome were at the Variety Studio, presented by Orville Redenbacher’s, at the Sundance Film Festival.
