Even though Fitzgerald is a traitor and murderer, Tom Hardy can't relate. He's a notably down-to-Earth actor and seemingly easy to get along with, which is what makes his acting in the film so good. It's easy to forget that it's Hardy under all of that grime and makeup!
The Gill-Man - Ricou Browning
The Creature From the Black Lagoon is a classic black and white horror film from 1954. Obviously, this film had no "special" FX since it was still so early on in movie history. The suit was sculpted entirely by hand, which completely disguised Ricou Browning inside of it.
