The 46-year-old "Mission Impossible" star said a role of the actress in the 2010 film "Winter Bone" gave the inspiration for Jaylah, reported Femalefirst.
Played by Sofia Boutella, the character is a new face in the Star Trek universe.
"Jaylah is actually named after Jennifer Lawrence in 'Winter Bone'. We were trying to create this very independent character. But we didn't have a name for it. So we just called it 'Jennifer-Lawrence-In-Winter's-Bone'," Pegg said.
While giving details of how whole name changed into Jaylah, Pegg said, "That's a long name. So it started getting tiring always saying, well Jennifer-Lawrence-In-Winter's-Bone is fighting here. So then we started calling her J-Law. And then she became Jaylah.
