Legend has all the elements of a period gangster film in place, along with dollops of additional dash and verve. It is stylish (the brothers are almost always in bespoke suits) and slick but somewhere down the halfway mark, takes a fearsome, dark twist. But more than anything else, it is a showcase for the formidable acting talents of Tom Hardy, last seen in the huge hit, Mad Max: Fury Road.

This is a reality driven film, brutish in evocation and as such, might not be pleasing to all.
