On August 1, 1983, Albert Magnoli arrived in Minneapolis to finish his revised screenplay for Purple Rain. He spent his first week in town interviewing the prospective cast members, including Prince’s band, the Time, and Vanity 6, to mine their real-life relationships for dramatic potential. As he explained to sessionographer Duane Tudahl, “My research was for me to sit down and say, ‘Okay, I have a scene I’m developing between you, Wendy, Lisa, and Prince, and you’re very angry at him. And you’re in the dressing room and you’re about to go on and you want to know if he hear[d] your music. Give me what you feel like?’ And they start, ‘Oh well, yeah that happens all the time!’ So all their shit comes up because they’ve been in that with him” (Tudahl 2018 117).
The director supplemented his research by sitting in on band rehearsals and attending the August 3 First Avenue performance where the film’s title song received its debut. Mostly, though, he wrote: spending his days in a motel room drafting in longhand, “from seven to seven… with a ruler and pencil, on paper. Then a secretary would come in and type everything up from that day in script form” (Light 2014 91). By the end of the month, when Magnoli flew back to Los Angeles to finish editing James Foley’s Reckless, his first draft was complete.
