Jessica Chastain Teases She Might Kill Some X-Men in 'Dark Phoenix'

Who suspected Jessica Chastain would wind up spoiling things for the upcoming X-Men movie Dark Phoenix? She really held nothing back in a recent interview on The Tonight Show With Jimmy Fallon.

In the interview with Fallon, Chastain hinted that her new character, who is being called "Smith," will be a definite danger to some X-Men. “Is your power for good or for evil?," Fallon asked.

“Well, I think the power’s for good, but other people might think it’s for evil,” Chastain responded. “I mean, I get to beat up a lot of X-Men in the movie.”

“Maybe kill some?,” she added coyly.

Fallon was astounded that Chastain was dropping so many teasers, considering most actors reply to questions with a noncommittal answer or no answer at all in fear they'd accidentally spoil something major.

“I didn’t say I definitely do,” Chastain clarified. “Maybe someone lives. Maybe someone dies.”

Dark Phoenix director, Simon Kinberg, explained previously that Smith is an alien, but that's about all he revealed.

"I can tease that she is not of this world, that she is an extraterrestrial character. I can tease that she does some pretty wonderful things with it," Kinberg said to Collider. "Beyond that, in terms of where she comes from specifically in our universe and what she’s based on in the comics, I guess I will say she’s sort of an amalgam of a couple different characters and iterations of those characters over the span of the different tellings of the Dark Phoenix story that have taken place."

Dark Phoenix comes out June 7.
