Everybody loves Jack Nicholson! And why not? He is the epitome of the charming rogue. Women want him, men want to be him.
His success is really astonishing since he's not an obviously attractive, Hollywood handsome type of guy. Short, balding, and with a giant head. But his eyes convey a sense of danger and playful, pranking wit that is extremely charismatic.
His list of roles is massive. From Chinatown to Batman to last year's Bucket List.
The only possible critique is that he plays the same character in every movie. But the world loves that character. We want to see the devilish Jack, and he keeps giving it to us. The man is an institution.
