The Invisible Man - 1933 - 7/10

The upside of the experiment renders one invisible.
Slight downside, insanity.
Dr. Griffin, working on “bleaching” fails to realize the compound he uses has been banned.
His deterioration runs from jokes to foul deeds to megalomania.
Pre-Code shocker owes a lot of Claude Rains’ voice.
Witty, devil-may-care, homicidal.
The effects are still impressive. Another early Universal gem.
Note: Surprising how well this worked out, considering its troubled history.
