Bobby Brown in Ghostbusters 2 (1989)
Director: Ivan Reitman
Before all the drama, Bobby Brown recorded the theme song "On Our Own" for the 1989 sequel Ghostbusters II. As a trade-off, the R&B singer was also given a 20-second spot as the door man for Gracie Mansion who asks for an extra proton pack for his "kid brother." Oh, the irony.
