Oh! What a wonderful film! The Invisible Man is fraught with witty dialogue, excellent character acting, inventive and creative special effects, insightful direction, and solid, tight scripting. The story is about a scientist that develops a serum which turns himself invisible, for good intent initially. The serum has negative side effects, one of which is turning the scientist into a raving,mad megalomaniac bent on conquering mankind and the world. What is most surprising about the film is its rather perverse sense of black humour(a James Whale specialty) and its cruelty. The Invisible Man is not a benign horror monster but rather a frightening, destructive force capable of acts of violence, madness, and viciousness. The direction is the real star of the film as Whale combines script, acting, mood, and setting amidst the background of ground-breaking special effects that are still impressive to this day. Whale laces his special humour throughout, and this film has no shortage of dark comedic moments. The acting all around is very good with people like Henry Travers, Gloria Stuart, Una O'Connor and William Harrigan especially as a jealous doctor giving all the support they can to a formless Claude Rains. Rains's voice is magnificent and one senses he was made to play the part that would make him famous. Look for Dwight Frye in a small role. A wonderful film experience!
