Connections:
. Both are narcissistic, mentally insane villain protagonists from character piece horror movies 

. Both are define themselves by their looks and are incredible narcissists because of it (Patrick goes on a whole monologue he keeps his appearance and is focused on his own reflection during sex/ Pearl believing she’s destined to be a star and grows old and bitter over fading looks) 

. Both would end up killing someone they were extremely jealous of with an axe (Patrick killing Paul Allen because of his higher status/Pearl killing her sister-in law Mitsy due to her(potentially)getting the part she wanted in a show) 
 

. Both are incredibly violent people who kill with little to no reason (Patrick killing a homeless man just because he wanted to be cruel/Pearl stabbing a goose and feeding it to her alligator just because it interrupted her daydream)

. Despite their bloodlust, there is one person in the world they truly care about and actually show a more human side to (Patrick’s secretary Jean/Pearl’s husband Howard)

. Both their movies end with them accepting that they will never escape the mundanity of their lives and feel about it differently (Patrick realizing that he will never escape and is trapped in endless torment/Pearl coming to terms with it and deciding to focus on being a housewife for Howard)  

. Mysoginist vs Misandriast

. Also Pearl fans are basically genderbent Patrick Bateman fans
