Which 1984 musical film was written by and starred Paul McCartney?

The 1984 musical film written by and starring Paul McCartney was Give My Regards to Broad Street. McCartney wrote the screenplay and supplied the music, while Peter Webb directed the British production.

The film presents a fictionalized day in McCartney's life. A set of master tapes disappears, and he spends the day trying to recover them before a threatened business takeover. The story mixes backstage drama with musical performances and fantasy sequences. McCartney appears alongside Linda McCartney, Ringo Starr, Bryan Brown, Barbara Bach and Tracey Ullman.

Its title plays on George M. Cohan's song “Give My Regards to Broadway” and refers to London's Broad Street railway station, which was central to the plot. The movie received poor reviews and performed weakly at the box office, but its soundtrack was more successful. It also included “No More Lonely Nights,” which received Golden Globe and BAFTA nominations for Best Original Song.
