Robert Downey Jr. is paying tribute to his father, Robert Downey Sr., who died Tuesday. He was 85.
"RIP Bob D. Sr. 1936-2021...Last night, dad passed peacefully in his sleep after years of enduring the ravages of Parkinson's ..he was a true maverick filmmaker, and remained remarkably optimistic throughout..According to my stepmoms calculations, they were happily married for just over 2000 years," Downey Jr. wrote on Instagram. "Rosemary Rogers-Downey, you are a saint, and our thoughts and prayers are with you."
