Not a lot of specifics are known about the film's plot as yet, though Deadline have heard that it will concern a warrior and his band of mystical cohorts on dangerous quest to find a mythical treasure. Which, to be sure, is just the sort of generic plot you might expect a Dungeons And Dragons movie to have, especially one trying to avoid releasing specifics just yet.
This one has been in development for a while, and was delayed when Hasbro filed a legal claim to the rights. Now, though, it appears to be back on track with David Leslie Johnson (Wrath Of The Titans) writing the script and Rob Letterman (Goosebumps) set to call the shots. How Elgort will fit in won't be known until he actually signs on the dotted line, but we would expect to keep hearing more about this one in the coming months.
Elgort, a stalwart of the Divergent films, will also be seen in Billionaire Boys Club and Edgar Wright's (The World's End) Baby Driver.
