It's once again morphin time. As if news of Nickelodeon's "The Splat" wasn't enough to get 1990s-era kids excited, filmmakers have begun to cast the 2017 movie reboot of the "Power Rangers" franchise. To date, four Rangers have been cast, with the latest being the Blue Ranger, who was announced Friday.

According to Variety, Lionsgate and Saban Brands announced they were starting to develop another live-action "Power Rangers" film, which would be the first in a series of movies. The plan is for a "re-envisioning" of the Rangers in modern times, as a group of teenagers unite to protect the world from alien invaders. The teenagers can turn into heroes and control giant robots to fight the invaders.

There have been numerous kinds of "Power Rangers" over the years, and with the new film coming out in 2017, one can expect to add yet another type to that list. Here's everything known so far about the new movie:

Rangers Cast: The official "Power Rangers" Twitter account has announced four of the six Power Rangers. Ludi Lin will play the Black Ranger, RJ Cyler the Blue Ranger, Dacre Montgomery the Red Ranger and Naomi Scott the Pink Ranger. The Yellow Ranger and the Green Ranger have yet to be announced.

Director And Writers: Dean Israelite will direct the film, while Ashley Miller and Zack Stentz will write the script. Miller previously worked on "Thor" and "X-Men: First Class."

Israelite told IGN he was "instantly drawn" to the movie. "I read the script and was really surprised by it and thought there was a really cool, contemporary, mature, but still playful, buoyant and fun take on the material, and [it] was updated in a really interesting way. It had this wonderful character that's essential to going on a fantastic adventure," Israelite dished.

Original Green Ranger: Fan-favorite Tommy, who went from being the Green Ranger to the White Ranger in the "Mighty Morphin Power Rangers" television series, is expected to have a cameo in the film. In an interview with ComicBook.com, actor Jason David Frank said he knows he'll be involved in the movie in some way, shape or form. "They talked to me about it," he said. "I don’t know how much I am involved, but for sure cameos at least in the reboot movie."

The Villain: The Power Rangers have done their job in taking out several villains over the years, but there is a major one who declared she would return and still hasn't. According to Collider, Scorpina is rumored to the the villain in the film, the minion of Rita. Scorpina is expected to attack the Rangers Morphin Grid, which harbors all of the energy of past and present Rangers.

"Dino Charge": Collider also reported the movie is expected to begin with the Dino Charge Power Rangers battling Scorpina. The film may not be a complete reboot, as Israelite dodged a question by IGN about whether the movie would exhibit continuity with the original TV series. Does that mean we might see the original "Power Rangers" Jason, Kim and Zach, as well as Tommy? In any case, the new characters are rumored to have the same names and traits as the original "Power Rangers."

Filming: ScreenRant reported "Power Rangers" will begin filming in Vancouver in 2016.

The Power Rangers became popular with the success of the Fox Kids TV show in 1993. Two feature films were later made, 1995's "Mighty Morphin Power Rangers: The Movie" and 1997's "Turbo: A Power Rangers Movie."

"Power Rangers" will be released in theaters Jan. 13, 2017.
