Deadline is reporting that the plans to adapt Insurgent into a movie are moving forward with Brian Duffield being tapped to write the script.
From Deadline:
Summit Entertainmentis certainly bullish on its adaptation of the Veronica Roth bestselling seriesDivergent. It not only has assigned the film the March 21, 2014 slot that got The Hunger Games off to a flying start, but it has officially gotten underway on the sequel. Summit has just set Brian Duffield to script the sequel,Insurgent, which Doug Wick and Lucy Fisher will produce the film via their Red Wagon Entertainment banner along with Pouya Shahbazian.
While we don’t know much about Duffield, this move to start working on the sequel while Divergent is still in production is indicative of how much confidence there is behind this franchise.
