Movie: It's A Wonderful Life (1946)
Villain: Harry F. Potter
Played by: Lionel Barrymore
George F. Bailey (Jimmy Stewart) is the ultimate good dude, constantly putting the needs of others before his own. The Laws of Movie Physics tell us that for every good dude there is an equal and opposite bad dude. Cue Mr. Potter.
Potter spends much of his adult life trying to undermine George while lining his pockets with that sweet sweet Bedford Falls real estate cash. After Uncle Billy, one of George's employees (never hire family, kids) taunts Potter, he accidentally leaves almost $10,000 in Potter's hands. What does Potter do? Sometimes, the worst thing you can do is nothing. He lays low, letting Bailey take the heat, nearly driving him to suicide. That's cold, bro.
