This comedy movie was first seen by me on TV in the 70s though the color quality makes me think it was created in the 60’s. The movie portrays a female ghost who loves a living guy. They both interact and may have been a couple before she died. Other ghosts make appearances in the movie too while a living suitor makes a play for the guy. Mischief thus occurs. At the end of the movie, the guy dies in a car crash, becomes a ghost too, and the couple is reunited in the afterworld. Any ideas?
