Before we go further, some clarification on where this film fits into the timeline. Let’s forget (for now) that there was a John Wick 4, because the events of “Ballerina” take place during the third movie. So, erase from your mind whatever huge, life-altering thing may or may not have happened in the last film. OK?

Anjelica Huston, Gabriel Byrne and Keanu Reeves also appear in Len Wiseman’s bloodbath of grief and revenge, in which an elite assassin doffs her tutu and goes rogue.
