A reader catches me scanting my research re Prince:
As I think I mentioned elsewhere, I think Prince brought an immense amount of wealth to Minnesota over the past 35+ years. He spent a lot here; he put us on the map musically speaking. He made four movies here, not two, as far as I can tell: Purple Rain, Graffiti Bridge, SIgn ‘o’ the Times, and Under the Cherry Moon.
Wikia (“The Home of Fandom”) confirms and adds a rumor of one more:
There is also a rumor that Prince appears for a few seconds in Batman (1989). He provided the soundtrack for the film and some fans believe you can see Prince crossing in the background of a scene, wearing a dark trenchcoat. Prince did visit the London set during filming for meetings with director Tim Burton so it is possible he made a secret cameo.
