“He was a goof,” Byrne, 37, tells PEOPLE Now. “He was such a goofy, funny, you know, adorable guy. He was incredibly generous. He had a huge heart. He was kind of, actually, really shy.”
“I mean we met each other when we were 18. We were kids. [He had a] kinetic energy. He was nonstop. I adored spending time with him,” she says, adding that their friendship represented “a really seminal part of my life, personally.”
Byrne, who stars in HBO’s The Immortal Life of Henrietta Lacks, is also “looking forward” to seeing the documentary I Am Heath Ledger. The film, which premiered at the Tribeca Film Festival on Sunday, provides an insightful look at Ledger’s life as a movie star and father, as well as his troubled final days.
“I know his sister Kate is in it, who’s fantastic,” Byrne says. “I’m sure it will be very heartbreaking, but it looks beautiful. I’m really looking forward to seeing it.”
