Murphy, who was credited as a "Strategic Guest Star", was added to the film after an original version was completed but tested poorly with audiences.
Best Defense was a major financial and critical disappointment.
Those who created Norbit did not set out to make a witty, comical masterpiece that made the viewers think and contemplate..is a comedy.
No one seems to understand it, be the long, winding and rather dull critical remarks on the movie bringing 'a new meaning to distasteful' or something equally as yawn-worthy, what needs to be realized is that this is riddled with clichés and fun, comical satire.
Murphy is also a singer, having frequently provided background vocals to songs released by The Bus Boys; the song "(The Boys Are) Back in Town" was featured in 48 Hrs.
