#5: Oliver Reed
Oliver Reed is best known for his intense parts in Gladiator (2000) and The Three Musketeers (1973), but his boogeyman reputation was further strengthened by his off-set behavior. He was known for his excessive drinking and ability to escalate physical conflicts. Reed believed that friendship could take the form of bar fights or wrestling matches, which always seemed to get out of control. There is a legend that he once redecorated a hotel room by tossing furniture into a swimming pool.
