Old Shame: Eddie Murphy trashed this movie while promoting Coming to America, saying the original script was far better than the finished product (indeed, the novelization is closer to what was intended).
In a brilliant example of Tropes Are Not Bad, Mel Gibson was considered for Jarrell. Face it: this movie has a rather cheesy and predictable plot, but it's being carried by Murphy's humor. Now imagine the movie without comedy but with Gibson.
John Barry wrote a score for the film, but it was rejected in favor of Michel Colombier's synthesizer music. Two Barry compositions remain in the soundtrack, one of those being Ann Wilson's "Best Man in The World" (La-La Land released the complete work of both composers).
