Rebel Wilson worked in a chip shop to prepare for her new role in 'The Brothers Grimsby'.
The 'Pitch Perfect 2' star - who plays Lindsey in the Sacha Baron Cohen film - got a taste of life in Grimsby, England by drinking in traditional pubs, working as a fish fryer and watching 'Benefits Street', which follows working-class people living off welfare.
She revealed: "For research, I watched the TV show 'Benefits Street', went to some English pubs, did karaoke and even worked in a fish-and-chip shop."
The 35-year-old comedienne was able to "relate" to the working-class characters in the movie as she came from a disadvantaged upbringing herself.
She told Cosmopolitan: "Coming from an underprivileged background myself, I can really relate to the working-class thing [in the film]."
Elsewhere, Rebel admitted she is "unique" and not your stereotypical Hollywood actress.
She added: "Being unique and different was a really good thing.
"When I walked into my agent's office for the first time [in 2009], they looked at me and said, 'Wow, we have nobody on our books like you.'
"And they signed me on my second day here."
