People make same observation as The Simpsons are turned into real life people for opening scene

Everyone is saying the same thing about The Simpsons' real-life opening scene.

As one of the longest-running shows on American TV, The Simpsons is one of the most widely beloved shows in the world, still going strong 35 years after its first episode aired in 1989.

Over the years, though, the show has gotten more and more creative with their iconic opening theme, including different details, animations, and sometimes characters from time to time - just to spice things up a little bit.

But one of the coolest and most memorable depictions of this was in 2006, when the creators made a live-action opening theme, take a look:

In the clip, we can see a boy playing Bart re-enacting the iconic blackboard scene, where he writes the same thing several times - though the sentence can change, depending on the episode.

This time, it read: "I will not eat things for money".

The man playing Homer nailed his role, chucking the radioactive stick to the side in tune with the theme song, while Marge (played by a woman with comparatively big hair) and Maggie are running errands, as per.

Lisa was played by a girl that pulled the band practice scene off to a tee, and at the end, they even had Homer run away from the car in real life - pure authenticity.

As cool as it was to see, everyone noticed one glaring detail of the memorable season 17, episode 15 opening theme.

It was a perfect shot-for-shot remake. (Fox)

Viewers think that the whole thing was actually filmed in the UK, despite the show being very much American-made.

They left their thoughts on this in the comments section below the clip, posted on YouTube.

One user said: "Although set in America, something about this is so unignorably British"

Another put: "I love how it's so clearly filmed in the UK as well, genuinely hilarious."

A third pointed out that a previously popular car in Britain featured: "I love the fact that homer is driving a Lada XD"

A different user said: "The British Homer Simpson driving a Russian car (LADA 2105 if I'm right) is so heartwarming".

But there is a very good reason behind why it seems so British.

The whole intro was created by a British company. (Fox)

It turns out that, despite being used for an actual episode of the series, it was created by Sky One, to advertise the premiere of Season 17 prior to its release.

In fact, at the end of the original sequence, it said: "Come home to The Simpsons on Sky One."

But creator Matt Groening loved it so much that he decided to use it in a real episode, adding the words 'The Simpsons' coming out of the clouds at the start.

It may have helped that the clip became a viral sensation online too - or as viral as something could have been in 2006.
