Robert Downey Jr. examines the life of his father, iconoclastic underground filmmaker Robert Downey Sr., in "Sr.," an intimate portrait of aging, parenthood and the way creativity is passed down through generations.
It's not quite warm and fuzzy but it is heartwarming, and Downey Jr. — one of the world's biggest movie stars, but also one of the most guarded — lets his defenses down and gives viewers a rare glimpse into his life and his upbringing.
Downey Sr. — he died in 2021 at age 85, after a battle with Parkinson's disease — was a counterculture creative whose films, including 1969's "Putney Swope" and 1975's "Two Tons of Turquoise to Taos Tonight," were ragtag, low-budget, experimental works that flew in the face of traditional values, both of the societal and filmmaking varieties.
