The Dead Poets Society star expressed his gratitude to Washington, who was already a veteran actor when he took on the role of Detective Alonzo Harris in the 2001 film, for his guidance.

"Thanks for all your wisdom," Hawke wrote in the post. "And happy birthday, Denzel."

Washington took home Best Actor at the 2002 Academy Awards for his role as Harris. He was the second Black actor to win in the category. Hawke was nominated for Best Actor in a Supporting Role.
