Berry had appeared in a couple of films prior to being cast in "Boomerang". However, after Berry performed her screen test, Murphy told Hudlin "well, that's it. There's no need to see the other two actresses because she's the part." Executives at Paramount Pictures were nervous about Robin Givens being cast in such a major role in the film, as she was disliked by many in the general public at the time because of her past relationship with Mike Tyson. Hudlin however, "thought that actually made her perfect for the role, that she was this formidable person, and a match for Eddie Murphy, who also had an intrepid reputation as a ladies' man. So, I wanted the audience to feel like this would be a fair fight." David Alan Grier and Martin Lawrence were cast as Murphy's best friends in the film. At the time, Grier was well known for the show "In Living Color". About him, Hudlin said, "I think he is an absolutely underrated genius. I think he is Steve Martin-level funny, and it's too bad more people don't know how to use his comic gift, because he is absolutely brilliant." Lawrence was brought on to the project after first working with Hudlin on "House Party", which was his first major role in a film. Bebe Drake-Massey and John Witherspoon had played a couple in "House Party", and were reunited for the film, this time playing the character Gerard's parents. Tisha Campbell also worked with Hudlin on "House Party", and was brought on board to play Murphy's obnoxious, and somewhat obsessive, neighbor. While on the set, Hudlin would always rave about Campbell and Lawrence, and Murphy suggested Hudlin do a film with the two of them. Lawrence, who was developing his television show at the time, overheard the two actors talking, and decided to cast Campbell as his girlfriend and later wife, Gina, for his hit sitcom "Martin". Grace Jones was cast in a role that was essentially written as a parody of herself. Of her work ethic, Hudlin said that "she was always 100% committed, and would do the absolute craziest thing at any given time. She was absolutely perfect for the role. It was written for her, and she came in very humble, very sweet." Eartha Kitt was the hardest person to cast for the film, as she was somewhat offended by her character's tone in the original script. Eventually she accepted the role, after some of the more tasteless jokes in the script were changed or removed.
