Cobra Kai Season Four Has Started Filming, Netflix Confirms

Sharing the exciting news on Twitter, Netflix also confirmed that a number of new cast members had been added to the line up.

The tweets read: "You ready? Lets begin! Season 4 of Cobra Kai is officially underway!

"A little more news - @veryvness and @peytonlist will be returning as series regulars, and we have some new faces joining us this season, Dallas Dupree Young and Oona O'Brien!"

For those of you who haven't seen it yet, Cobra Kai stars William Zabka and Ralph Macchio reprising their respective Karate Kid roles as Johnny Lawrence and Daniel LaRusso.

And despite being set more than 30 years after the tournament that changed their lives, the rivalry between the two of them reignites.

Netflix originally acquired the first two seasons of the show in June last year, which were first aired on YouTube Premium.

The third season premiered on Netflix in January.

According to the show's stars, the young ensemble cast means the story could run for another three seasons yet.

Macchio told LADbible: "The writers have always felt they had six seasons in their head, where the story arcs can go.

"So that should all land when the time is right.

"You don't want to overstay your welcome, but the fans are having fun and there's more story there.

"As long as we're allowed to keep doing it, Billy and I are in."

Zabka - who is an Academy Award nominated writer as well as actor - said the nostalgia for the film through an army of younger fans has been surreal.

He said: "Karate Kid has sustained and grown in pop culture over the decades but there's a real feeling of the sprit of the '80s coming back - music and fashion.

"My own kids love it. It's cool to be a part of that resurgence.

"I'd definitely like to write for the show too. But we have our heads pretty full with being in front of the camera.

"But at the right time, it's definitely a possibility."
