A lively, absorbing documentary about the Italian composer whose music is featured in hundreds of movies, from “A Fistful of Dollars” to “Kill Bill.”“The Good, the Bad and the Ugly,” “Days of Heaven,” “Before the Revolution,” “1900,” “The Untouchables,” “Kill Bill,” “Django Unchained,” “The Mission,” “The Thing,” “Fists in the Pocket,” “The Battle of Algiers,” “The Bird With the Crystal Plumage,” “Bugsy,” “Bulworth,” “Tie Me Up! Tie Me Down!” — if you’ve watched a movie in the last half century there’s a good chance that you’ve heard music by Ennio Morricone, the titanic Italian composer and arranger who helped define films as we know and hear them.When Morricone died at the age of 91 in 2020, it seemed almost hard to believe given how expansive his reach had been and, well, how long he’d been part of my movie life. (His death was announced with a statement he titled: “I, Ennio Morricone, am dead.”) When I was a kid, we had an LP of his soundtrack for Gillo Pontecorvo’s “Burn!” (1970), a period epic about a British intelligence officer (Marlon Brando) who’s sent to a fictional Portuguese colony to stir up trouble. A audiocassette of the soundtrack is stashed somewhere in my house; every so often, I listen to it on Spotify and am again transported by Morricone’s soaring music.In “Ennio,” a lively, absorbing documentary about the composer, Morricone discusses his work on “Burn!” and so many other films. Written and directed by Giuseppe Tornatore, it is a crowded, hyperventilated portrait stuffed with archival and original material, including interviews with Morricone shot in 2015 and 2016. Like several other filmmakers, Tornatore worked repeatedly with Morricone, a partnership that began with “Cinema Paradiso” (1990), the director’s soppy heart-tugger about a friendship between a theater projectionist and the boy he schools who becomes a filmmaker. It’s perhaps no surprise that “Ennio” is another cinephilic paean.With help from Morricone, whose interviews anchor the documentary, Tornatore ably fills in the composer’s family history, though the details become sketchier as the musician’s fame steadily grows. Morricone’s father, Mario, was a trumpet player, and soon Ennio was playing it, too. He began composing music as a child and studied it formally at a conservatory in Rome, where one of his teachers was the composer Goffredo Petrassi. A force in Italian modernist music, Petrassi became a towering figure for his student, the embodiment of a serious patrimony that seemed (to some) at odds with Morricone’s commercial work.One of the movie’s nice surprises is that Morricone turns out to be a total charmer, a low-key showman with a demure gaze that he works like a vamp and an impish smile that routinely punctuates one of his anecdotes. The movie opens with him speed walking in a circle inside a spacious, elegantly shambolic apartment before pausing to execute some calisthenics. It’s an amusing introduction that suggests Morricone’s vitality and determination, as if he were preparing for another leg in the extraordinary marathon of his life. Or maybe he was warming up for this movie, which runs 2 hours and 36 minutes, though never feels like a slog, even with its frustratingly unmodulated pacing. There’s much to see and to hear, most of it delightful.Among the most engaging sections are those involving Morricone’s work with Sergio Leone. They first collaborated on Leone’s “A Fistful of Dollars,” a western set in Mexico, shot in Spain and starring a television actor on hiatus, straight from Hollywood, named Clint Eastwood. Although Morricone and Leone shared some history, they were not initially on the same wavelength when they started work on the film. Leone was reinventing the genre and drawing liberally from many of his adored influences. He lifted the story from Akira Kurosawa’s “Yojimbo” (Kurosawa later sued), and Leone told Morricone that he wanted to use some music from Howard Hawks’s “Rio Bravo” for the climatic duel in “Dollars.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
