You've likely experienced that most magical of moments when an actor strides out in front of the camera, puts in a performance for the ages in one epic scene, and successfully only goes and steals the entire damn movie.
And if you haven't, quickly go and treat yourself to this list here.
But what about those talented actors who unfortunately didn't manage to blow away audiences with their work in one specific sequence, and actually ended up regrettably doing the complete opposite?
Everyone is allowed a bad day at the office, folks. It's just a shame that this bunch of otherwise quite awesome performers went and had theirs whilst the cameras were rolling on a big-budget blockbuster or hotly anticipated drama.
And these performances during one scene in particular often ended up being so disastrous, trying to enjoy the rest of the flick they belong to became an almost impossible task, sadly.
Again, it's important to note that nobody sets out to do a terrible job. But that still won't wash away the memories of the following actors completely spoiling their movies thanks to their part in one particularly dreadful scene.
10. Hayden Christensen's Creepy Flirting - Star Wars - Episode II: Attack Of The Clones
After years of being on the receiving end of waves of criticism for his work in George Lucas' prequel trilogy, Hayden Christensen has finally found himself being largely celebrated by Star Wars fans for both his performances in those Episodes and turns in the likes of the Obi-Wan Kenobi and Ahsoka series.
However, even with all of that deserved love being fired his way after all these years, there's still one specific exchange during Attack of the Clones in particular that even the most passionate Christensen lover would struggle to defend.
Completely failing to sell the idea of Padme Amidala having no choice but to fall in love with the maverick Jedi Anakin Skywalker, the way the young actor attempted to flirt his way through Lucas' admittedly excruciating sandy dialogue on Naboo will never not be a tough watch.
This middle chapter in the prequel section of the Skywalker Saga was obviously built around establishing the cause of Darth Vader's eventual rise - that being the death of his beloved Padme one Episode later.
But this first creepy flicker of love just forces you to cringe instead of swoon and pretty much killed the central romance of Episode II and III before it had even properly started.
