The film sees Mark Strong (Kingsman: The Secret Service) as M16 super spy Sebastian Graves, with Baron Cohen as his gormless brother Nobby. The pair have been separated for many years but to Sebastian's obvious chagrin, they have been reunited. Nobby means well but he is more bushel than lantern in the smarts stakes, and his unofficial occupation – England football hooligan – is a source of embarrassment for his sibling.
Nobby lives in Grimsby with his 11 kids and girlfriend (Rebel Wilson), but what he wants most of all is to have his brother back in his life. But on his quest for a reunion he stumbles upon a terrorist plot that makes him suddenly indispensable. God help us all.
Directed by Luc Besson (Léon: The Professional) protégé Louis Leterrier (Now You See Me), Grimsby also stars Penélope Cruz (Volver), Isla Fisher (Now You See Me), Rebel Wilson (Pitch Perfect) and Gabourey Sidibe (Precious).
Grimsby will land in UK cinemas on 24 February.
