Actor Keith Carradine has been a mainstay in TV and film for decades, and he has some pretty wild inside Hollywood stories to share.

He currently plays the president on CBS drama “Madam Secretary,” and recently appeared in such hit TV shows as “Fargo” and “Dexter,” but his Hollywood days go way back. He talks about the time he made out with Madonna onscreen after she requested that he co-star with her in her “Material Girl” video. Back then, there were rumors that he and Madonna had a thing, but he insists that it wasn’t true – he was married with two kids at the time!

That’s not all Keith shared about his days in Tinseltown -- watch the video above to find out what movie Keith calls “one of the great disastrous moments in pop culture” and check out the video below to hear Keith talk about finally getting a chance to co-star with his famous daughter Martha Plimpton after 40 years of waiting.
