People still cannot get over the real-life age gap between Keira Knightley and Thomas Brodie-Sangster in 'Love Actually'

We are just a couple of weeks away from the most wonderful day of the year. A time for indulging in delicious foods, spending quality time with loved ones, exchanging gifts, oh, and for putting on your family's go-to Christmas movie.

Whether it's a classic film you're after, a guilty pleasure kids movie, or a romantic comedy, there really is a festive movie for everyone.

And one of the most beloved Christmas movies out there is Richard Curtis' 2003 rom-com Love Actually.

The beautifully made flick is perfect for the holiday season. It's just all kinds of heartwarming and one you can watch with all the family - and it really does star a plethora of famous faces.

From the late Alan Rickman making Emma Thompson (and the rest of us) cry with his infidelity, to Hugh Grant making us all laugh as he dances around Number 10 to 'Jump' - there really is something for everyone.

In fact, the movie includes nine intertwined stories about complicated relationships and the pursuit of love - and two of the most heart-wrenching are that of Kiera Knightley and then child-star Thomas Brodie-Sangster.

Feast your eyes on the most adorable moment in Love Actually:

In the film, Knightley plays Juliet, who is unknowingly involved in a love triangle with her husband Peter, and Peter's best friend, Mark (played by Andrew Lincoln).

And, without a doubt, the cutest love story in the movie is that of schoolboy Brodie-Sangster - who plays Sam in the festive flick, who has fallen in love with American classmate Joanna (Olivia Olson).

However, no matter how popular the movie has remained, people on social media still cannot get over the real-life age difference between actors Knightley and Brodie-Sangster.

At the time of filming, Brodie-Sangster was just 13 years old and looked remarkably fresh-faced. Meanwhile, Knightley - who played an actual married woman in the movie, was only 18.

This, of course, means that there was just a five-year age gap between the two actors - despite appearing to be an entire generation apart in the movie.

In any case, every Christmas, this revelation is enough to make people flock to Twitter and share their dismay.

Replying to another tweet about Brodie-Sangster, one Twitter-user wrote: "I can't get over the fact that he was only 5 years younger then Keira Knightley in Love Actually. He def didn't look 13... Just..."

And in response to another tweet about Brodie-Sangster's timeless appearance, one person typed: "Mad when you think that Kiera Knightley was only 5 and half years old than him in Love Actually..."

And the tweets just continue to roll in...

One user posted a meme that read, "Okay, was anybody going to tell me that there is a 5 year age gap between Thomas Brodie-Sangster and Keira Knightly [sic] / or was I just supposed to find that out on Twitter myself?"

"He looks 5 and she looks 25," added another.
