Johnny Knoxville banned the Jackass cast from drinking while filming their latest movie to show support for his recovering alcoholic co-star STEVE-O.
The oddball prankster was forced to face his substance abuse demons in 2008 after Knoxville staged an intervention and begged him to check into rehab.
The stuntman turned his life around after a stint in Dr. Drew Pinsky's Los Angeles clinic and when the wacky crew reunited to begin filming Jackass 3D in January (10), Knoxville made sure it was a sober affair.
He says, "(Steve-O) hasn't drunk for two years so we ensured there was no booze lying around. We went to the bar after work, not during."
