John Witherspoon's scenes were added after filming had wrapped. Eddie Murphy demanded that scenes with Witherspoon be added to the film. Witherspoon picked his outlandish wardrobe himself and improvised his lines.
Halle Berry was the only actress to audition for the part of Angela. Eddie Murphy and Reginald Hudlin cast her immediately after seeing her screen test.
The studio was nervous about Robin Givens being cast as Jacqueline. At the time, she was labeled as a cold-hearted golddigger by the media and the general public during her marriage to Mike Tyson. Reginald Hudlin felt her public image made her perfect for the part because she could be seen as a strong woman who could control Marcus.
The soundtrack album to Boomerang was tremendously successful on the music charts and is widely considered a magnum opus of Black R&B music in the early nineties. The soundtrack sold three million copies, achieving triple-platinum status. The album was executive produced by L.A. Reid and Kenneth 'Babyface' Edmonds and features mainly contemporary R&B, urban soul, new jack swing, hip-hop soul and several popular, chart-topping ballads that are considered classics by R&B / Soul artists such as Toni Braxton, Boyz II Men, PM Dawn, Johnny Gill, and Keith Washington.
Production went very well, and as expected with so many comic actors and personalities around, was very lively. During production, Reginald Hudlin said that whenever David Alan Grier and Martin Lawrence worked, the film's crew usually worked a little slower because wherever they were, there would be so much comedy being generated, and they were so funny that everyone wanted to hang out near where they were throughout the day. In the scene where the new fragrance is being presented to Strangé, the director said that "what Grace was doing on the set while we were shooting was so funny that I remember Halle crying off-camera, cause she was trying to keep a straight face but she couldn't. So, whenever she was off-camera, she would just be literally crying because she was laughing so hard. And fortunately, for her reaction shots she was able to recover."
