Recently, after Prince’s death, writer/director Albert Magnoli was asked about the film’s (and its namesake song’s) title: “I’m not sure, but if you have ever been to Minneapolis, you know that the weather can be quite extreme, and they have very dramatic, torrential downpours. Just before a fierce storm, clouds would begin to churn and roil. Prince would grab me and take me outside. We would stand together in a field just looking up at the sky. It would change color from dark gray to blue, and finally to purple. And then the sky would open up and down came the rain. These memories will be with me forever.” The same can be said about memories of the artist who is so alive in his first film, loosely based on early chapters of his own story, complete with abuse, romance, rivalry, and the beginnings of a massive musical career.
