I actually saw The Invisible Man (1933) shortly after I saw the James Whale bio-pic Gods and Monsters (1998), starring Ian MacKellan and Brendan Fraser. So it was with that image of the director in my head that I watched this film. Claude Rains (Casablanca) is perfectly cast as the mad scientist/invisible man. The remainder of the cast, though not really challenged much, are more than serviceable in what they are required to do. As has been mentioned by most of the other posters, the special effects hold up rather well even today. An amazing feat considering the film is over 70 years old! The DVD has several interesting documentaries / commentaries that made me appreciate not only this film's entertainment value but its historical significance as well.

People tend to use the word "classic" too freely. I can't help but laugh when I hear some of the movies that people call "classics". The term gets thrown around so much that it often looses some of its importance and real meaning. I try to reserve "classic" to a select group of films that I believe have achieved a certain status and have withstood the test of time. And I have no problem putting the label "classic" on The Invisible Man.

James Whale made a lot of great films in the 1930s. Some (Frankenstein and Bride of Frankenstein, for example) may be better known, but I've always thought of The Invisible Man as the best of the bunch. It's got everything. Terrific performances, incredible special effects, nice comedic touches, and technical brilliance are found in abundance throughout the film.

• Terrific Performances: For someone who only has a few seconds of actual screen time, Claude Rains is amazing. His voice creates such a presence that at times it's easy to forget that he's not actually there. As for Una O'Connor, I've seen some people complain about Whale's use of her, but I think she was never better than in The Invisible Man. She's great whether playing the proper landlord showing a new guest to his room or as the overly hysterical woman afraid for her life. The rest of the cast, especially E.E. Clive and Gloria Stuart, is exceptional.

• Incredible Special Effects: It's amazing to revisit The Invisible Man and see how well the special effects have withstood the passage of time. They were state-of-the-art in 1933 and they remain impressive today. It took some real craftsmanship to pull-off the invisibility gags seen in The Invisible Man. To me, none is more impressive than the first time we get a glimpse under the bandages while he's eating and we see no lower jaw. Impressive stuff!

• Nice Comedic Touches: Billed as a horror film, The Invisible Man actually contains more scenes of humor than horror. I've already mentioned O'Connor, but she's only a small part of the humor in the film. The police, the various frightened passersby, and even Claude Rains himself add to the fun found in The Invisible Man. I'm of the opinion that it never goes overboard, but fits nicely into the plot.

• Technical Brilliance: Beyond the special effects, the film is wonderful from a technical standpoint. Lighting, cinematography, and set design are incredible and some of the best of the 30s. Everything looks perfect. In my opinion, Whale never did better. I've always been impressed by the way Whale used his camera as part of the action when many of his contemporaries seemed content with the "plant it and shoot" style of film-making.
