Arnold Schwarzenegger became the governor of California, Cristiano Ronaldo made his Manchester United debut and we were still a year away from the release of Mean Girls. Yes, 2023 may seem like yesterday but it most definitely wasn't.

Here are 10 films that you won't believe actually turn 20 years old this year. Eeek.
5. The Room
"Do you understand life? Do you?". The most unlikely of success stories, Tommy Wisseau's 'best worst movie ever' has become a cult classic with movie goers and has spawned a number one best selling book and a film - The Disaster Artist - based on the making of the film. Oh hai! | Greg Sestero

7. Lost In Translation
In many ways, you either love Wes Anderson's movies - or you don't. However, 2003's Lost In Translation seemed a hit across the globe, gaining an almost perfect 95% on Rotten Tomatoes. | Getty Images Photo: Ernesto S. Ruscio
8. Oldboy
Is this really two decades old? One of the finest - some would say the best - pieces of Korean film sees a man locked in a building for years on end for no apparent reason. When he is released, he goes on a voyage of revenge to discover who locked him up - and why. Includes one of the most iconic fight scenes in cinema history. We can't quite believe it is 20 years old. | Getty Images
