Matthew McConaughey says 'Killer Joe' made him want to "clean himself with a steel-brush".
The 'How to Lose a Guy in 10 Days' actor admits the crime thriller - which contains suggestions of incest and a lot of nudity - was a far reach from his romantic-comedy past and made him feel "sick".
He said: "It made me feel sick. I didn't like it at all. I felt it was gross."
The Texan-born actor - renowned for playing light-hearted roles in Hollywood - admits he wanted a particular eye-watering scene involving Gina Gershona and a chicken drumstick to "go down in cult history".
He added: "After the first take I think I blacked out or was seeing stars. I was excited to go to work that day. I had the chance to do one of those scenes that could go down in cult history.
"It's scary to do but it was a real go-for-it scene."
The 42-year-old star plays the lead role in the 2012 movie, and while he is renowned for playing more light-hearted characters, he is hoping 'Killer Joe' will define a new chapter for his career.
He told the Guardian newspaper: "I'm hanging my hat on reality and humanity, not morality. I didn't go after 'Killer Joe'. Billy Friedkin came to me for it."
