Our "relationships" with actors are one-sided: while we may feel emotionally connected to them through their performances, we do not know them personally and idealize a "perfect" version of them that doesn't exist in real life.
To remind themselves that everyone is flawed, people created a discussion on the subreddit r/Fauxmoi, where they have been listing the stars who have supposedly shown that they might be difficult to work with.
(Some of the things they've been saying are more factual, as mainstream media have covered them, while others lean towards the he-said-she-said end of the spectrum. As with everything online, take these claims with a grain of salt before forming your own opinion of someone. However, it's important to remember that celebrities, like everyone else, can be complex and sometimes behave in ways that seem contradictory.)
