Jack Nicholson's portrayal of the Joker in Batman was universally praised by critics with The Hollywood Reporter writing at the time, "It is difficult to imagine any other actor performing this character as well".
But Nicholson wasn't director Tim Burton's first preference to play the villain in the 1989 movie, according to John Lithgow.
The 3rd Rock from the Sun star told Vulture that he was originally offered the role but turned it down, a career move he thoroughly regrets.
"I have never told anyone this story, but I tried to persuade him [Tim Burton] I was not right for the part, and I succeeded," Lithgow said.
