Fans of the Divergent films, which are based on the books by author Veronica Roth, finally get to see the last chapter of the series on the big screen this weekend, or at least half of the last chapter. Like so many series-films have all done since the filmmakers behind Harry Potter split the final book into two movies, this final chapter, Allegiant, will also be split into Parts 1 and 2, with the second installment expected in theaters next year. Allegiant – Part 1 picks up after the conclusion of Insurgent, and finds the protagonist Tris Prior and Four trying to escape over the wall surrounding futuristic Chicago in order to discover what is hidden behind the other side. Insurgent director Robert Schwentke (FlightPlan, Red) returned to direct the new installment, working from a screen adaptation by Noah Oppenheim (The Maze Runner, Jackie), Adam Cooper and Bill Collage (Accepted, Exodus: Gods and Kings). Starring in the series are actors Shailene Woodley (The Descendants, White Bird in a Blizzard), Theo James (The In-between Movie, Underworld: Awakening), Naomi Watts (King Kong, J. Edgar), Octavia Spencer (The Help, Fruitvale Station), Jeff Daniels (Dumb and Dumber, The Martian), and Zoe Kravitz (Dope, Mad Max: Fury Road). Watch the trailer one more time before you see the movie in theaters, and have a safe Saint Patrick’s Day weekend!
