I think that Noel Clarke's career is over. 20 testimonies: that's too big.

In the case of John Barrowman, so far, it sounds like exhibitionism, naturism, histrionics & immature pranks... Certainly, it is not a correct behaviour but Clarke threatened some of the women that he harassed. That's bigger.

Also, in the case of Barrowman, it would have happened in 2005, 15 years ago. In 2008, he had already apologised for a similar incident:“I apologise for any offence I have caused. I was joining in the light-hearted and fun banter of the show and went too far. I was wrong to do this and it will never happen again.”

Everybody remembers what happened to Hugh Grant. It didn't end his career.
