I think he did pretty well. Other drunk/high actors get angry to grab people they should not. This appears to be tipsy-drowsy drunk, not shouty-punchy drunk. He still came to set. He was dressed. They got the shot in the end. All those extras (paid by the hour) were probably perfectly happy that it took longer than expected.
>> I told him that I had to put him on camera for insurance reasons, so that we could show that he was all over the place and that we couldn’t do the job — that way we’d have insurance coverage for the day because of the actor malfunctioning. He understood, so I helped him out of the vehicle; he held onto my arm and we walked in.
Being drunk is certainly unprofessional, but few modern celebs would push though, embarrassing themselves on camera, to satisfy the needs of the shoot. A drunk yes, but still a pro imho.
