When the two-time Golden Globe winner took to the stage to accept his Outstanding Performance by a Male Actor in a Leading Role award, he took time to recognize his predecessor in the role.
"I'm standing here on the shoulders of my favourite actor, Heath Ledger," he said in a heartfelt comment.
Heath won a posthumous Oscar for his work in The Dark Knight after tragically passing away from a prescription drugs overdose in 2008.
Joaquin also thanked Christian Bale, Heath's co-star in the aforementioned film, for his work playing Batman in Christopher Nolan's trilogy, which he said had been inspirational to him in Joker.
"You never turn in a bad performance, and it's infuriating" he said, prompting Christian to laugh in appreciation. "I wish you would. Just suck once."
