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.
And is there anything that makes you feel older than discovering one of your favourite films is infact 20 years old? Well...maybe, but it certainly doesn't give us a youthful glow.
Here are 10 films that you won't believe actually turn 20 years old this year. Eeek.
9. Underworld
A movie that threw Kate Beckinsale into the limelight and became an instant horror classic as werewolves were plunged into battle with vampires. Spawned many sequels and still stands the test of time. | Getty Images
10. House of 1000 Corpses
This Rob Zombie horror is now heralded as one of the best in scary movie history - and deservedly so. Made two decades ago but hasn't aged a wink - and is wonderfully gory. | Getty Images
