One thing that big Hollywood stars will often say is that they don't like watching their own movie performances, even when attending glitzy red carpet premieres. Instead, once the shoot for a movie is done, they dodge the finished product like it's a bullet.
Actors like Johnny Depp, Reese Witherspoon, and Adam Driver have admitted to this in recent years, and it's completely understandable why.
Like the rest of us ordinary folk, it's hard to accept that the work we do is actually good, so we tend to only notice the "mistakes" - even if there aren't really any mistakes present.
Actors are clearly no different in this regard, and the ones who do watch their own movie performances are often extremely critical of them, sometimes going as far as saying that they dislike them, cringe at them, or full-on hate them.
While some of these performances are genuinely quite bad, some of them are actually really, really good (and one we haven't even seen yet!), but for various reasons, the actors in question just don't agree.
We really are our own worst critics.
10. Sam Worthington - Clash Of The Titans
Despite all of its flaws, 2010's Clash Of The Titans is a really fun movie. The action scenes come thick and fast, and there's just something mindlessly entertaining about watching a bunch of sweaty dudes fight against giant scaly monsters.
But star Sam Worthington? He doesn't have a single nice thing to say about it.
In fact, he even went so far as to apologise for the film in a 2010 interview, acknowledging that it let a lot of people down, while also vowing that the sequel - which hit cinemas in 2012 - would be a vast improvement. Spoilers: It wasn't.
Worthington also took shots at his own performance in Clash Of The Titans, stating that "I think I can act f**king better, to be honest", which, credit where credit is due, is a belief that he went on to demonstrate in movies like Everest, Hacksaw Ridge, and Fractured.
But Clash Of The Titans? Yeah... that wasn't his finest moment.
