Bulletproof has been cancelled. I'm not surprised, Clarke's name is so intrinsically interwoven with the show. All I can say is I feel sorry for all the other cast members and production team losing out on so much work:
Like shops, offices and factories, tv and film sets are workspaces and I'm frankly astonished anyone who repeatedly exposed his penis to his colleagues was allowed to continue working in those spaces, no matter how he and others justified and laughed the behaviour off.
Sometimes tv and film sets require actors to be nude, and for their colleagues to be present. There was an early episode of Doctor Who where Barrowman’s character was required to be naked.
It can make for fuzzy boundaries, which can be exploited by those with a mind to do so. Fairly obviously Barrowman is an exhibitionist, equally obviously the direct feedback his antics were getting from cast mates and crew in the moment was laughter and enjoyment. It’s so hard to speak up and say that you are uncomfortable in a room full of people laughing, because it makes you the killjoy.
That produces a culture that perpetuates the fuzzy boundaries around appropriate behaviour.
However, I don’t think the same can be said of the NC allegations. He can’t have been under the impression that his behaviour was enjoyed or welcomed given that people refused to work with him after and directly told him to stop.
