Filming is now under way on the project. The movie will focus on Tinker Tailor Soldier Spy, Sherlock Holmes and Syriana actor Mark Strong, playing a government agent who is forced to go on the run with his estranged idiotic brother. The sibling, who will be played by Sacha Baron Cohen, happens to be a football hooligan connected to the lower league football club Grimsby Town.
Annabelle Wallis, who plays Grace Burgess in Peaky Blinders, will portray Baron Cohen's girlfriend in the film.
Details about the characters the actors will play are currently being kept under wraps.
Grimsby has been written by Sacha Baron Cohen, Peter Baynham (Borat) and Phil Johnston (Wreck-It Ralph). It is being directed by Louis Leterrier, who has previously overseen Now You See Me, Clash Of The Titans and The Incredible Hulk.
Grimsby is being made by Four By Two Films, the same company that has been involved in most of Baron Cohen's other film projects. Baron Cohen is acting as producer, alongside Shaun Of The Dead and Hot Fuzz's Nira Park.
Further details about the film are expected to be announced officially later this year.
