In an interview with Sacha Baron Cohen in promoting the movie, SBC said of the English town of Grimsby: "Grimsby is a lovely town in the North of England, which is twinned with the city of Chernobyl. I'm very proud of it - it was recently declared number three in the whole of Europe for childhood obesity and we just became the first town in England to achieve 100 per cent unemployment. Grimsby's a friendly place, where the little things that strangers say matter a lot. Like a 'please', a 'thank you', a 'not guilty'."
In an interview, Sacha Baron Cohen said of Donald Trump's appearance in the film: "Yeah, Donald, he loves my work," he sighs. "When I called him up, he was very excited. He worked for about a week; he was great. We gave him a wrap gift and he worked for minimum wage." He laughs. "No, (the footage [of Trump in the film]) wasn't real. We didn't get permission."
None of the shots in Grimsby were actually shot in the town, they were all shot in Essex. Cohen never asked to shoot in the town.
The look of Sacha Baron Cohen's character, most particularly the hair and sideburns, is heavily reflective of that of Liam Gallagher, frontman of world famous 90s-00s rock band Oasis. The pair had a dispute around 2012. Cohen later said: "I thought to avoid confrontation by having my hair done like him in my next movie." The Mirror newspaper also reported that Cohen "based his look in [the] new film Grimsby - Attenti a quell'altro (2016) on the former Oasis frontman".
According to website Crossmap, ". . . opening at number 8 and grossing only [US] $3.2M has put The Brothers Grimsby at [No.] 36 of the worst openings ever for movies released in at least 2,000 theaters".
