Steven Spielberg's box office smash hit E.T. the Extra-Terrestrial remains one of the most iconic sci-fi movies of all time and will forever go down as a cult classic. The friendly extra-terrestrial won the hearts of audiences across the world - leaving pretty much everyone an emotional mess during the final moments of the movie (we still can't watch that movie without bawling our eyes out).

But just when you thought E.T. had gone home for good, in what's possibly the best Christmas commercial we've ever seen, the beloved alien has returned to earth once more to see his friend...

Keep scrolling to take a look at the brand new commercial that's captured the hearts of fans everywhere.

In fact, by 1983, E.T. surpassed Star Wars as the highest-grossing film of all-time, by which point it had raked in a whopping $619 million in revenue worldwide.

And it's not hard to see why...

The movie featured an acclaimed ensemble cast including the likes of a then 7-year-old Drew Barrymore, Henry Thomas, Dee Wallace, and Peter Coyote.

The cult classic chronicles the story of E.T, an alien who is left behind on Earth...

When a small group of alien botanists visit earth during the night to gather plant specimens, they are forced to flee back to their ship when government agents appear.

Elliott, along with his siblings agree to keep E.T. hidden from their parents.

Soon, however, E.T. falls ill, resulting in government intervention forcing Elliott to figure out a way to help the friendly alien escape Earth.

The movie's final scenes are a real-tear jerker.

Thankfully, E.T. successfully finds his ship and is able to return home - but of course, before he leaves Earth, he bids his friends an emotional goodbye.

It's been thirty-seven years since E.T. left Earth.

But a brand new Christmas commercial sees the beloved alien reunite with his friend nearly 4 decades on and it's everything we could ever want.

The festive spectacle kicked off with Elliott’s kids finding E.T. lurking in the garden behind a snowman.

After letting out some pretty ear-splitting screams (can you blame them?), their dad rushes out to help, but he quickly becomes overjoyed with happiness when he sees his long-lost pal standing in his garden.

"You came back?!" Elliott emotionally exclaims.

Okay, someone please pass the tissues...

After giving E.T. a proper introduction to his family...

Elliott invites E.T. indoors where he is quickly schooled on all things virtual reality, the internet and of course, Christmas.

Made in collaboration with Universal Pictures, the main theme of the advert is to "reconnect this Christmas."

With so many families spending the holidays apart for various reasons, the fictional reunion is utterly heartwarming.

Of course, E.T. has some fancy intergalactic regalia to share with his friend too...

At one point, the alien pulls out a holographic spinning ball that shows presumably his own alien family. "Family!" Elliott says. "Home," E.T. responds, a little nod to the movie's iconic line.

Sadly, his trip had to come to an end.

And there was only one way to get him back to his ship - the group travel through the air by bike as the iconic soundtrack plays out. And just like in the movie, as he says his goodbyes, E.T. points his glowing finger at Elliott’s son’s heart and promises that "he’ll be right there." Our hearts...
