Divergent stars Theo James and Shailene Woodley have had a lot of fun together on the promotional trail, but when they joined EW’s Sara Vilkomerson for an Entertainment Weekly Radio special, James learned there was one thing he did during prep for the film that annoyed her (for, okay, just a day). In the clip below, the duo also talks about filming some of their big stunts in the movie, which is in theaters now, and the injuries Woodley sustained.
UPDATE: In the video below, James and Woodley also reveal which faction they’d choose.
Tune in to EW Radio (SiriusXM 105) on March 21 at 1 p.m. and 7 p.m. ET to hear the full Divergent special.
