Michael Keaton on relationship with Batman costar, Jack Nicholson

Michael Keaton got candid on the bond he developed with his Batman costar, Jack Nicholson after the latter played the role of Joker in the second Keaton-Burton collaboration after Beetlejuice.

“I just really liked him,” Keaton, who is still in touch with the three-time Oscar winner, opened up to People.

“He’s really, really intelligent. Really. A real reader. Just has an innate intelligence, and then a self-taught intelligence. … Because he devours books. Always something to talk about. Very opinionated about things when you’re in a conversation.”

Keaton also looked back at all the partying they did back at the time.

“He took me to Paris in a jet,” recalled Keaton. “I was like a Boy Scout. I was ready to go out like a normal person. Jack didn’t get out of his room until like 10 p.m. or 10:30.”

Reminiscing about ending up at the exclusive Les Bains Douches nightclub, Keaton said, “Jack was having a ball. He had the biggest grin on his face,” Keaton recounted.

Returning to the hotel before his host, the actor recalled thinking, “‘This is fun, but it’s kind of wasted on me.’ ”
