While Divergent had its share of action-packed scenes, it seems like the sequel isn't keen on toning down the peril for the heroes. Some of the film's stars talked about how dangerous some of the stunts got and what fans can expect action-wise.

Speaking with E! Online, stars Shailene Woodley and Ansel Elgort talked about the work they had done for Insurgent's action scenes and the toll it took on them physically.

"This scene is amazing. We're doing the train scenes where we get to run and jump on a moving train and I haven't rehearsed this," Woodley said. "Everyone else had a chance to rehearse this and today's my first time kind of seeing the set and it's been really exciting."

Elgort added that one scene in particular left him "physically exhausted" afterwards. "Yes, jumping on a movie train at 10 m.p.h. is not an easy thing to do and it's definitely physically exhausting," Elgort revealed. "Every time I do it I'm really tired."

Insurgent follows Tris (Woodley) as she searches for allies and answers in the dystopian ruins of a futuristic Chicago. Tris and Four (Theo James) are now fugitives on the run, hunted by Jeanine (Kate Winslet), the leader of the power-hungry Erudite elite. Racing against time, they must find out what Tris's family sacrificed their lives to protect, and why the Erudite leaders will do anything to stop them.

Haunted by her past choices but desperate to protect the ones she loves, Tris faces one impossible challenge after another as they unlock the truth about the past and ultimately the future of their world.

Insurgent is set to open in theaters on March 20, 2015.
