Robert Downey Sr. is getting his documentary due.

The late actor and filmmaker's son Robert Downey Jr. profiles his father in the upcoming Netflix film Sr., which explores Downey Sr.'s life and his impact on both Hollywood and the life of his son.

"I just remember that cacophony of creativity, but mostly laughter," Downey Jr., 57, says in the trailer that dropped Monday.

Directed by American Movie documentarian Chris Smith, Sr. is "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," according to an official synopsis.

The synopsis goes on to say that 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."

Sr. was filmed over the span of three years, and made its debut at the Telluride Film Festival in September.

In the movie, the Avengers: Endgame star turns the camera on his relationship with his father during his decline with Parkinson's disease — revealing a far more vulnerable portrait of one of the most famous stars in the world.

"The film truly honors Senior's nonlinear, outlaw-life approach, including capturing his decision to embark on his own concurrent and final film project," the synopsis describes.

It concludes, "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."
