Keith Richards offers up a wistful look at life in Netflix’s trailer for “Keith Richards: Under the Influence.”

“Life’s a funny thing,” he notes. “No one wants to get old but no one wants to die young, either.”

The iconic guitarist for the Rolling Stones, who was a heroin addict in the 1970s, continues to perform at the age of 71.

“A lot of guys want to play like Chuck Berry,” he muses. “That’s like taking on the devil. I’ll take it on.”

Netflix releases the documentary on Sept. 18, a day after its world premiere at the Toronto Film Festival. The film follows Richards on the road during the creation of his first solo album in 23 years, “Crosseyed Heart,” and offers up interviews with his musical collaborators, who include Tom Waits and musician/ co-producers Steve Jordan and Waddy Wachtel.

The film includes a journey to Chicago — where Richards first encountered Buddy Guy, Muddy Waters, Howlin’ Wolf and Chess Records — and to Nashville, where Richards details  his long love of country music.

“Under the Influence” is directed by Morgan Neville, who received an Academy Award in 2014 for the documentary “Twenty Feet From Stardom.” Neville’s credits also include documentaries on Pearl Jam, Johnny Cash and Ray Charles.

Neville is producing the film, along with Justin Wilkes (“What Happened, Miss Simone?,” “Under African Skies”) and Jane Rose (“Crossfire Hurricane,” “Shine a Light”).
