Claim: The Divergent Series: Allegiant is part of something.

The Divergent Series : Allegiant is a 2016 American action adventure film directed by Robert Schwentke with a screenplay by Bill Collage , Adam Cooper , and Noah Oppenheim . It is the first of two cinematic parts based on the novel Allegiant , the final book in the Divergent trilogy by Veronica Roth , and the third installment in The Divergent Series .   The film stars Shailene Woodley , Theo James , Jeff Daniels , Miles Teller , Ansel Elgort , Zoë Kravitz , Maggie Q , Ray Stevenson , Bill Skarsgard , Octavia Spencer and Naomi Watts , and is the sequel to Insurgent and could be followed by the concluding entry , Ascendant -LRB- Allegiant and Ascendant were originally to be titled Allegiant -- Part 1 and Allegiant -- Part 2 -RRB- .   Allegiant was released on March 18 , 2016 , in theaters and IMAX and received mainly negative reviews . The film was a financial disappointment , grossing $ 179 million worldwide , becoming the lowest-grossing Divergent film . This led to budget cuts on the fourth and the possibility that the final installment in the series , Ascendant , would be released as a TV movie instead of a theatrical one .
