CANNES, France — Twenty-five years after premiering “Pulp Fiction” in Cannes, Quentin Tarantino returned to the French film festival with neither great vengeance nor furious anger but a gentler fairy tale about 1960s Los Angeles.

“Once Upon a Time In … Hollywood” made its much-anticipated debut Tuesday in Cannes, giving the festival its most concentrated splash of celebrity and frenzy. The film’s two stars, Brad Pitt and Leonardo DiCaprio, brought a fittingly old-school Hollywood glamour to the Cannes red carpet, where throngs of onlookers swelled along the Croisette.

Much of the plot of “Once Upon a Time In … Hollywood” had been carefully kept under wraps leading up to the premiere. DiCaprio plays a Westerns actor anxious that his notoriety is slipping. Pitt plays his stunt double, friend and, because of a drunk driving offense, his driver. Though set against the backdrop of the Manson Family murders, much of Tarantino’s film is invested in recapturing the radiance of a bygone Hollywood.

Tarantino’s First Movie Not Released by Harvey Weinstein

For a filmmaker often associated with blistering dialogue and ecstatic explosions of violence, “One Upon a Time in … Hollywood” finds the 56-year-old Tarantino working at a more relaxed pace, spending generous amounts of time in odes to spaghetti Westerns and ’60s TV shows.

Ahead of the premiere, Tarantino, whose “Pulp Fiction” won the Palme d’Or in 1994, issued a statement to festival audiences imploring them not to spoil the film for future moviegoers — a request repeated before the film’s press screening. Journalists lined up hours in advance.

“Once Upon a Time in … Hollywood” is Tarantino’s first movie not being released by Harvey Weinstein. After Tarantino cut ties with the disgraced mogul, the project attracted the interest of most studios. Sony Pictures landed the film and gave it a $95 million budget — a very rare gamble on a high-priced original movie.

Instead of superheroes or intellectual property, “Once Upon a Time in … Hollywood” will instead bank on the draw of Tarantino and his two movie stars. Margot Robbie also co-stars as Sharon Tate.

“Once Upon a Time … in Hollywood” will be released in U.S. theaters July 26.
