The distinctive sideburns have returned! Following Black Caesar’s earlier success, this film was quickly made with the intention of capitalizing on the demand for Blaxploitation films. Unfortunately, it is obvious that the movie was hastily produced and feels incomplete. The story brings Fred Williamson back as Tommy Gibbs (who has apparently been brought back from the dead), as he confronts a corrupt D.A., Diangelo (Gerald Gordon), while also navigating romantic relationships. Directed by Larry Cohen, any assessment of Hell Up In Harlem should begin with his candid admission that it’s essentially a ninety-minute collection of scenes. And he is correct. The film progresses in an abrupt and episodic manner, alternating between conversations and energetic action sequences. This pattern continues throughout the entire movie. The fact that the action is engaging—along with some memorable lines—prevents it from becoming entirely unwatchable. There’s also a degree of admiration to be had for this style of filmmaking; it was clearly shot spontaneously. Despite the unbelievable plot elements, the abundance of bright red fake blood, and the clumsily performed stunts, the brutality of the violence elevates the film above mediocrity. In fact, there's an undercurrent of questionable taste in the violent events, with the main character’s actions going unpunished, which is characteristic of Blaxploitation movies. It's flawed, but it provides entertainment within its genre. 6/10
