Actor Michael Keaton has starred in five films directed by Tim Burton, but admits there’s one role he’s not very fond of.

“I love working with Tim so much, but I don’t think we ever really analyzed why we work pretty well together; we just do,” Keaton told the New York Times. “I think I let him down on one movie, but that’s just me, and it bugs me to this day. I was clueless on ‘Dumbo.’ I sucked in ‘Dumbo.’”

Burton, who also took part in the interview, didn’t agree.

“I don’t even know what you’re talking about, but whatever,” he said.

Keaton played amusement park owner V.A. Vandevere in the live-action retelling of the Disney classic.

Their next collaboration, “Beetlejuice Beetlejuice,” hits screens Sept. 6.
