Jessica Chastain says Tilda Swinton inspired her 'Dark Phoenix' character as she can imagine the star "ruling over some planet".
The 42-year-old actress plays the mysterious 'Smith' in the 'X-Men' film - an "other-worldly creature" with the ability to shapeshift - and Jessica revealed that Tilda inspired her alter ego as she's an "elevated form of a human being" that she can imagine "ruling over some planet".
Speaking on 'The Graham Norton Show', she said: "I play an other-worldly creature. I was told I am not allowed to say that I play an alien, but basically I play an alien. I am a shapeshifter, so I am supposed to look like an elevated form of a human being. The one person I think of that way is Tilda Swinton. I'm not convinced she's a human being! I think she is ruling over some planet somewhere like the goddess she is."
'Dark Phoenix' is a direct sequel to 'X-Men: Apocalypse' and the seventh and final instalment in the main 'X-Men' series. The plot follows Sophie Turner's Jean Grey as she loses control of her abilities and unleashes the 'Phoenix'.
Michael Fassbender - who will reprise his role as Magneto in the film for the fourth time - went on explain that it "feels good" to be coming to the end of the franchise, and feels it was the right time for Jean Grey to take centre stage.
