SR. explores the life and work of pioneering underground filmmaker Robert Downey Sr., whose work on films like PUTNEY SWOPE and GREASER’S PALACE set the standard for countercultural comedy during the tumult of the 1960s and 70s. The film also unpacks personal themes ranging from creativity and mortality to fatherhood, and generational trauma, with Downey Sr.’s relationship with his son, Robert Downey Jr., playing a key role in this formally daring, unflinching, yet loving portrait of an artist unbound by the limitations of commercial moviemaking.
