Robert Downey Sr., father of Robert Downey Jr., has died at age 85.

Downey Sr., who had been battling Parkinson’s disease for more than five years, died in his sleep Wednesday morning at his New York City home, his wife Rosemary Rogers told the New York Daily News.

Rogers was at home with Downey Sr. when he passed away.

Downey Jr. paid tribute to his father on Instagram, writing: “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 stepmom’s calculations, they were happily married for just over 2000 years.

“Rosemary Rogers-Downey, you are a saint, and our thoughts and prayers are with you.”

The filmmaker and actor was best known for roles in movies such as “Boogie Nights”, “Magnolia” and “To Live and Die in L.A.”.
