Some people are clumsy and a bit scatterbrained, and one of the most famous examples of the phenomenon is Harry Potter's Neville Longbottom, who has many things go wrong for him throughout the course of the popular series.
But despite its popularity, the actor who brought Neville to life, Matthew Lewis, said that it's "painful" to watch himself in the Harry Potter movies.
The now 31-year-old explained that he doesn't find his performance painful to watch because he thinks that it's bad, but rather because it reflects too much of his own personality.
In an interview with The New York Times, he said: "I find it quite difficult when too much of me starts to come through in a character.
"It's easier when I can play someone completely different, like a police officer in London or someone who's wealthy.
"At times it's painful how much of me there is in Neville. When I'm watching, I'm like, 'That's not Neville; that's you.'"
However, while Lewis might find his portrayal of Neville difficult to watch, there are other members of the Harry Potter cast who look back on their child acting days with a lot more yearning, like Tom Felton, who played Draco Malfoy.
He proved this by posting a photograph of his current self next to a portrait of him portraying the young Draco, hilariously proving that in real-time, even the most famous child actors can't avoid getting old like the rest of us.
Felton captioned the picture: "Agings a b**ch [sic]."
But while it's been two decades since Felton first brought Draco to life in 2001's Harry Potter and the Philosopher's Stone, he's still as popular as ever and the post received well over 1.4 million likes.
Tom Fletcher of McFly commented: "You'll always be beautiful to me TF."
But Lewis, who has become a heartthrob since he appeared in Harry Potter, jokingly commented: "Speak for yourself lad!"
Lewis married his wife actress Angela Jones in 2018, with the pair unbelievably meeting at a Wizarding World event at Universal Studios, Bustle reports.
"I never believed in soul mates until we met," Jones wrote of Lewis on her blog. "We came from two different countries, 4,334 miles apart, and yet we were one and the same. A few months after meeting, he proposed to me in Paris during my first trip abroad. Yes, it’s been that kind of fairytale thing."
