The actioner is now said to be on "a fast track" to production, with a script from Shay Hatten, who penned the most recent Wick flick, John Wick:Chapter 3 - Parabellum.
Casting for the rest of Ballerina is now unknown but we are fairly certain that Angelica Huston will be reprising her role as The Director, who helps train young ballerinas into femme fatales (much like the Red Room from Marvel where Black Widow was trained). Whether Reeves will appear in the film is anyone's guess at this stage.
John Wick:Chapter 3 - Parabellum was described by NME's Alex Flood in a review as "a brutal, blood-soaked sequel". I have no idea how much ballet experience Wiseman has, but he probably got the gig based on the fact that he was one of the guys behind the female-driven action franchise Underworld, which starred Kate Beckinsale as a gun-toting vampire.
The movie will be directed by Len Wiseman, who previously made Live Free or Die Hard and Total Recall. He has most recently been engaged in directing series which range from Hawaii 5-0 to Lucifer, Sleepy Hollow, The Gifted and Swamp Thing.
