It could loosely be described as a spoof to the scene, but isn't as obvious as the airplane or naked gun films. the film stars an early Chris Rock who was coming straight from his success in New Jack City, who plays the films leading character Albert Brown. Along with his two 'homies', they are the most hopeless rappers that has emerged on the rap scene in LA and are desperate for the 'big break' to set off their career. Then one night they are showcasing in a club and meet the notorious rapper MC Gusto, which gives them the idea to relaunch themselves as 'gangster rappers'. Things take a turn for the best and they suddenly are catapulted to stardom, with serious consequences. From then on in, the film really takes off and features cameos from Ice-T, Ice Cuve, MC Ren and Public Enemys Flavor Flav and Chuck D. If you like gangster rap, then this is the film for you.
