When it premiered on July 27, 1984, the rock drama “Purple Rain” announced the arrival of a major movie star in Prince Rogers Nelson, a flamboyant 26-year-old musician better known by the royal mononym Prince. Already a multi-platinum recording artist, Prince’s feature debut grossed a whopping $70 million in the U.S., while its Grammy winning soundtrack spent six consecutive months atop the Billboard charts. On the 30th anniversary of its release, here’s why “Purple Rain” remains the crowning musical film of our time.

The Album

Included in The Library of Congress’s National Registry of recordings deemed “culturally, historically, or aesthetically important,” this era-defining collection of hits sounds as fresh today as it did three decades ago. From the joyful exuberance of “Let’s Go Crazy” to the bittersweet sorrow of the classic title track, the film’s music became the soundtrack of a generation.

The Kid

While most newcomers may have chosen a safer character to play their first time out, Prince took a chance by portraying his on-screen alter-ego, The Kid, as a deeply troubled, self-destructive artist spiraling out of control. And yet those same dark qualities made audiences root for him. By the time he’s redeemed on stage during the climactic performance, the risk made perfect sense.

MTV

The fledgling cable channel was only three years old when “Purple Rain” took it by storm in the summer of ‘84. Early on, notably few black artists were featured in its rotation. Prince, along with fellow trailblazer Michael Jackson, helped break the perceived color barrier. Before long, videos and behind-the-scenes footage from “Purple Rain” ran virtually day and night.

Director Albert Magnoli

With only an award winning short to his credit, Albert Magnoli was personally tapped by Prince to helm his debut feature. Working as director, writer and editor, Magnoli ushered “Purple Rain” into theaters eleven months later, where it unseated “Ghostbusters” from number one at the box office. The director and star collaborated again in 1987 on the concert film “Sign ‘o’ the Times.”

Morris Day

Part antagonist, part comic relief, the lead singer of the dance-funk ensemble The Time managed the near-impossible task of stealing scenes from the charismatic Prince. Dapperly dressed and hilariously profane, Day’s energetic performance of “Jungle Love” is one of the highlights of the film. 17 years later, he reprised the song in Kevin Smith’s “Jay and Silent Bob Strike Back.”

Apollonia

Though her role was originally written for pop star Vanity, and then offered to Jennifer Beals, 25-year-old Apollonia Kotero provided Prince with a believable love interest, something that his future co-stars Kristin Scott Thomas (“Under the Cherry Moon”) and Ingrid Chavez (“Graffiti Bridge”) were unable to offer. Razzie nomination aside, her sunny presence humanized the hero.

The Sex

Between the hardcore lyrics of “Darling Nikki” and a custom-built guitar that literally ejaculates fluid onto the audience during the film’s climax, “Purple Rain” pushed erotic boundaries to the limit. The love scenes between Prince and Apollonia proved so intense that the MPAA reportedly rated the film X, before several seconds were trimmed to earn it an R.

The Style

Designed by Marie France, who’d previously collaborated with Prince on several music videos, the costumes in “Purple Rain” mixed an androgynous punk aesthetic with the ruffle and lace of 18th century French royalty. Dynamically lensed by cinematographer Donald Thorin, the film’s rich color palette of deep black, blinding white and spectral violet gave it a look like no other.

Minneapolis, MN

Shot on location in and around Prince’s Midwestern hometown, “Purple Rain” eschewed the glamour of Manhattan and the glitz of Los Angeles in favor of a working class setting that grounded the semi-autobiographical film in gritty reality. Eminem took a page from its book 18 years later by filming “8 Mile” in his birthplace of inner-city Detroit, Michigan.

The Purple Motorcycle

Like Peter Fonda’s red-white-and-blue chopper in “Easy Rider,” or Steve McQueen’s fence-jumping Triumph in “The Great Escape,” Prince’s customized Honda with purple front-shield and hot pink inserts was more than just a means of transportation. Featured prominently on the film’s poster and the album’s cover, it’s among the most iconic movie motorcycles of all time.
