What was the name of Prince's 1990 film that he wrote, directed, and starred in?

Prince's 1990 film that he wrote, directed, and starred in was Graffiti Bridge.

The film is an American rock musical drama and a standalone sequel to Purple Rain. Prince plays The Kid, the central character, while Morris Day returns as his rival. The story revolves around competing clubs and a struggle over control of the fictional Seven Corners area.

Graffiti Bridge was filmed largely at Paisley Park and in locations around Minneapolis. Its title came from a real bridge in Eden Prairie, Minnesota, which was later demolished. Like Purple Rain, the film was accompanied by a soundtrack album featuring Prince and several guest performers, including The Time, Mavis Staples, George Clinton, and Tevin Campbell.

A common mix-up is choosing Purple Rain, Prince's better-known 1984 film, or Under the Cherry Moon, his 1986 directorial debut. Graffiti Bridge was Prince's third and final major theatrical film role. It was poorly received commercially and critically, although the soundtrack earned considerably stronger reviews.
