Actor Christian Slater really got into character for his new role as a crystal methamphetamine addict - he insisted on sleeping rough on the set.
The star totally immersed himself in the character of Delgado in Rites of Passage and gave up nights at home with his family to get into the head of a desperate men.
He tells WENN, "I slept on the set. I was a crystal meth addict in the movie. I didn't take it to that level of course but I would sleep on location.
"It was one of the more fun characters I've gotten to play because he hallucinates and sees things and ends up talking to this sock monkey that rides around on a shotgun. It was crazy."
