Veteran good guy actor Tom Hanks let down his guard, perhaps unintentionally, and dropped an F-bomb live on Good Morning America as he was promoting his new movie Cloud Atlas.

“Mostly it’s swear words,” he joked. Hey, can’t say he didn’t warn us. After some urging, the actor acquiesced and gave a taster of what he called his incomprehensible dialect, accidentally including a heavily accented “f–k” in the middle of his made-up word spew.

GMA host Elizabeth Vargas immediately apologized to GMA viewers as Hanks seemed a bit surprised by his potty mouth.

“We are so sorry, America,” she said, as the equally shell-shocked Hanks looked past the camera and said, “Man, oh, man.”

“I’m sorry,” he jumped in. “I slipped into a brand of acting. I have never done that before; I apologize to the kids in America that are watching this right now, and let me say that the next time I’m on the show there will be a seven-second delay.
