The Invisible Man is a filmmaking marvel. First off, R.C. Sherriff’s screenplay sets things up speedily and without much exposition. The film introduces Claude Rains’s character through everyone else’s point of view–first the strangers he meets, then his familiars–all while Rains is front and center in the film. Even though he is, after all, invisible.
Rains is another marvel. The script is excellent, Whale does a peerless job directing (more on his contributions in a bit), but Rains makes the whole thing possible. With him, Invisible isn’t some horror picture or a sci-fi one, it’s a very simple, very tragic story of a man going mad. It doesn’t need the special effects, it just needs Rains. Everything else is a bonus. It’s an outstanding performance.
The whole cast is great–Gloria Stuart has to sell the idea Rains was once a lovable guy, so goes Henry Travers for instance. William Harrigan gets to be a sleaze bag but a decent enough minded one.
Now for Whale. Many of the special effects in The Invisible Man are unbelievable. Even the ones where they obviously used some kind of matte decades are sort of unbelievable, but the practical effects–where the bandages must have been suspended by wire–those are astonishing. And Whale knows, early on, to wow the audience. But he never lets up with it; it’s one wow after another.
The Invisible Man gets better on every viewing. The work from Whale, Rains and Sherriff is singular.
