There's two things I really liked about The Invisible Man (1933): its special effects and the cast's complete confusion on how to act in a scene with special effects.
It felt like every character in this movie had lost their mind. Especially the innkeeper's wife who was constantly hysterical.
The be fair, she was dealing with a lot of shit.
Plus, the police and townspeople were accused of having lost their minds. And, of course, the invisible man had gone mad himself. Evidently, being super into strangling people is a side effect of invisibility.
