  • Hawke will be next seen in the crime thriller "The Guilty"

Ethan Hawke, who worked with the late Robin Williams in the teen drama "Dead Poets Society," thought his co-star was "incredibly irritating." Hawke assumed that Williams also thought the same about him.

The 50-year-old actor revealed that Williams was habitually making a lot of jokes on the set and as an 18-year-old teen star, at that time, he found it irksome.

"I thought Robin hated me. He had a habit of making a ton of jokes on set," he said, Variety reported. "At 18, I found that incredibly irritating. He wouldn’t stop and I wouldn’t laugh at anything he did."

Hawke further recalled that it was Williams who helped him get his first agent, "[Agent] He called, saying, ‘Robin Williams says you are going to do really well."

The "24 Hours to Live" star further recollected, "There was this scene in the film when he makes me spontaneously make up a poem in front of the class. He made this joke at the end of it, saying that he found me intimidating. I thought it was a joke."

"As I get older, I realize there is something intimidating about young people’s earnestness, their intensity. It is intimidating – to be the person they think you are. Robin was that for me," he added.

On the work front, Hawke will be next seen in the crime thriller, "The Guilty." Netflix dropped the first trailer of "The Guilty" starring Jake Gyllenhaal on Twitter Sunday.

He will also feature in the horror thriller, "The Black Phone," which is based on Derrickson and C. Robert Cargill's adaptation of the book with the same name. The movie is helmed by Scott Derrickson and it is slated to release on Jan. 28, 2022.

Hawke is currently filming a television series, "Moon Knight," which is a superhero series based on Marvel Comics. The miniseries is created by Jeremy Slater and it will stream on Disney Plus in 2022.

Williams, on the other hand, was last seen in 2014's "Night at the Museum: Secret of the Tomb." He also lent his voice to an animated movie, "Absolutely Anything," which was released in 2015.
