Douglas was said to have made the remarks during an interview with The Guardian, who say they stand firmly by the quote, and that Michael was not misrepresented in any way.
The Guardian then published the audio of the interview, and the transcript of the comment. Below is the Q & A between Michael Douglas and The Guardian film writer, Xan Brooks.
Brooks: “Do you feel, in hindsight, that you overloaded your system? Overloaded your system with drugs, smoking, drink?”Sounds to me like he said it!
Douglas: “No. No. Ah, without getting too specific, this particular cancer is caused by something called HPV, which actually comes about from cunnilingus.”
