Los Angeles - Scarlett Johansson intimidated her Under the Skin cast mates.
The 29-year-old actress - who recently stepped down from her role as an ambassador for children's charity Unicef in favour of a sponsorship deal with SodaStream - seduces a large number of men in the film, and as the actors playing them were mostly amateur, she says they found her intimidating.
She said: "These characters that I'm picking up are those forgotten guys - they don't have any ties. They're not like the coolest kid in school.
"So the guys I was working with, it helped [their performance] that they'd be like, 'I can't believe I'm sitting next to you.' "
Scarlett also revealed that she felt uncomfortable whilst watching the film in which she plays a seductress who preys upon hitch hikers, and said she tried to pretend she wasn't watching herself on screen.
She said: "It was strange. I felt really anxious. I didn't know what the film would look like at all. I tried to watch it as an audience member. And it pulled me into it."
The Avengers Assemble star - who got engaged to French journalist Romain Dauriac last year following her divorce from Green Lantern actor Ryan Reynolds - filmed Under the Skin in the Scottish Highlands and admits she tried some of the local delicacies.
She told SFX magazine: "I don't eat red meat so I tried the vegetarian haggis. It tasted like stuffing. And Irn-Bru - that's got a kick!"
