It will be a long time before you see any of it, but production on Season 4 of Netflix's Cobra Kai has officially begun. The streaming service announced the beginning of filming by sharing a photo of the Season 4 premiere script, titled "Let's Begin." The news didn't stop there, as Netflix also revealed some changes to the show's cast.

First and foremost, Peyton List (Tory) and Vanessa Rudio (Carmen) have both been made series regulars for Season 4, after previously appearing in recurring roles. That means Miguel's mother (and Johnny's love interest) should be around a lot more often, as will Samantha LaRusso's eternal rival, Tory.

Additionally, two new cast members have been added to the roster. Dallas Dupree Young, who recently appeared on Netflix's The Big Show Show, starring new AEW commentator Paul Wight, has been cast, as well as newcomer Oona O'Brien.
