Filmmaker and actor Robert Downey Sr., father of actor Robert Downey Jr., has died. He was 85. Downey Jr. wrote on Instagram that his father died late Tuesday in his sleep at home in New York. He had Parkinson’s disease for more than five years. Born in New York City in 1936 as Robert Elias Jr., he later changed his surname to Downey—his stepfather’s name—in order to enlist in the army early. After the army, he got into filmmaking by chance while living in New York with his sister. The last film he directed was the 2005 documentary “Rittenhouse Square,” about a small Philadelphia park. The elder Downey is also survived by his wife, bestselling author Rosemary Rogers.
