But finding the perfect actors to portray these two men in the popular book’s film adaptation was an “exhausting” process, according to director Matthew López.
“It was about a five-month, very consistent search for both these characters,” López told PEOPLE in 2023. “I saw hundreds — I mean, quite literally hundreds and hundreds — of actors for it. And because the thing that compelled me to make this film was the characters, I knew I couldn’t make the film unless I had the two perfect actors for the roles.”
