It's a serious struggle, in my opinion.
There are cases like
Nathan Fillion, where anonymous sources claimed stuff like this:
(Regarding Fillion's treatment of Stana Katic on the set of "Castle")
Stana would cry on set because Nathan was such a bully to her
Stana would go in her dressing room and cry. A lot of people who work on the show dont like Nathan. Its not just her
Nathan has been nasty to Stana for a long time. Stana was a pro, just wanted to get in there and do her job.
As far as I know, nothing sticks. Even Stana denied these claims.
I mean, you'll never know. Maybe, in turn of recent events (Weinstein, #metoo), she might come forward and make even worse accusations but as of now, Nate is safe for me.
Then there is
Tom Cruise: A man with what seems to be an incredible work ethic who also happens to be the poster boy for Scientology, with a less than decent track record of handling the women in his life.I still watch his movies but I get a lot of shit for supporting him this way. Maybe rightfully so.
Jackie Chan - Damn, what is it with this guy? Does he really believe the stuff he says, whenever he talks about China related stuff, or is he just a shill for the People's Republic? I admire his work, especially all the pre-2000 stuff, and I'm not sure how to judge him.
Roman Polanski - LOL, fuck him!
I really love the "Dance of the Vampires" musical (the German version, not the TERRIBLE US-version). While it's based on the Polanski movie, Roman had no creative input on the musical (again, as far as I was able to verify). Steve Barton is (well, was - R.I.P.) my favourite singer of all time and I was blown away to hear an
American perform German lyrics with so much care and emotion. I just can't hate this musical, never will. I don't watch Polanski's movies though.
Mel Gibson - This guy is nuts and maybe the actor I'm most conflicted about. I enjoy his performances and I appreciated him on The Expendables 3. I'd even go as far as to claim that he steals that movie.
These are just some examples but detaching the art from the artist is sometimes easier said than done.
