The preview video shares Downey Sr.’s active participation in the creation of the documentary, including offering notes and weighing in on the title.
With past shots of the two generations, the trailer hints at Downey Jr.'s struggle with substance abuse, which almost cost him his acting career.
The documentary essentially pays homage to Downey Sr.'s career and personal life, including his intimate yet complicated relationship with his son.
Downey Jr. shared the documentary's poster on Instagram with the message, 'He was a groundbreaking filmmaker as well as my dad. It's not uncomplicated. Sr. is a documentary that tells the story of Robert Downey's maverick rise in NYC, his crash and burn and redemption in Hollywood and our relationship in the aftermath.”
