If you know the very basics of the Marvel Cinematic Universe, it’s highly likely that you know superstar Robert Downey Jr. played a pivotal role in bringing that whole thing to life. What people often forget is that Iron Man was the culmination of a comeback in Downey Jr.’s career, which had its origins with the work of his family – especially his father's, Robert Downey Sr. Titled simply Sr., a Netflix documentary will chronicle the life and relationship of both the stars over the course of three years.

In the heartfelt trailer released today, it is revealed that even though Downey Sr. had episodes of uncomfortable pain (he died from complications related to Parkinson’s disease), he did his best to keep his laid-back sense of humor most of the time. The documentary is led by Downey Jr., who decided that the legacy of his family of filmmakers deserved to be documented, celebrated, and shown to the world.

In addition, the trailer reveals that Downey Sr. had an active participation in the making of the film, going as far as giving notes, asking for additional takes, and even weighing in on the title. The trailer also shows that the project will provide some blunt interviews with the Roberts, and they won’t shy away from Downey Jr.’s infamous substance abuse problem, which could have ended his film career.

Sr. is directed by five-time Emmy nominee Chris Smith, who has a knack for finding incredible stories to tell. In the last few years alone, Smith either directed, produced, or did both with titles like Tiger King, Bad Vegan: Fame. Fraud. Fugitives, and Jim & Andy: The Great Beyond. In an official statement, Smith revealed why he chose a funny and irreverent approach to an otherwise sad story of Downey Sr.'s final living years:

“Knowing what I know now, it’s really the only way you could attempt to make something on the two Downeys. Larger than life, but open and human as ever, it was such a pleasure and life-affirming experience to capture some glimpses of the highs, lows and everything in between.”

Netflix premieres Sr. on December 2. You can watch the trailer below:

Check out the official synopsis here:

From documentarian Chris Smith (American Movie) comes a lovingly irreverent portrait of the life, career, and last days of maverick filmmaker Robert Downey Sr., whose rebellious spirit infused decades of counterculture movie-making. “Sr.” widens the lens from Downey’s art to the life with which it was deeply intertwined, including an intimate examination of his relationship with son Robert Downey, Jr. Shot over the course of three years, the film truly honors Senior’s nonlinear, outlaw-life approach, including capturing his decision to embark on his own concurrent and final film project. Smith’s portrait of a family and an artist is a meditation on life that’s as surreal as it is sentimental, a celebration of making art with no rules that tosses out its own rulebook along the way.
