To me what this says is that Lionsgate has lots of faith in Schwentke to finish the series.
He was only confirmed for the first part but most likely he’ll direct both parts. We’ll have to wait and see for that.
Noah Oppenheim, who also scripted YA adaptation “The Maze Runner,” is adapting the first part of “Allegiant,” which, like predecessors “Harry Potter,” “Hunger Games” and “Twilight,” is being split into two films.
Allegiant Part 1 has a March 18, 2016 release date.
