Matthew McConaughey plays hitman Joe Cooper in Killer Joe

Matthew McConaughey nearly turned down the role of Joe Cooper in new movie Killer Joe.

The 42-year-old actor was shocked when he first flcked through the script of the crime thriller.

'First read I didn't get it. I was appalled by it. I thought it was gross,' says Matthew.

'I then realised it was a dark, dark comedy.'

In one shocking scene in the film, actress Geena Gershon, playing a trailer park stepmother, gets to her knees to fellate a piece of chicken that's strapped to Matthew's groin. 

'Honestly man, it was a blast,' Matthew tells Metro.

'That's a scene, when you get the schedule, you look forward to.

'Never seen anything like that before.'
