Rhys Ifans stars as Britain's most notorious drug smuggler, Howard Marks, in this loosely factual biopic, based on (and sharing its name with) Marks's 1996 autobiography, from director Bernard Rose (Candyman, Immortal Beloved).
The narrative tracks the illicit career of Oxford graduate Marks (Ifans) from its early days in the 1970s, when he discovered his teacher training course was never likely to match the money and excitement that came from importing marijuana into the UK, through his bumbling rise to being the world's top dope runner, and on to its inevitable shuddering halt, thanks to the law.
Along the way, his eclectic contacts include the IRA's Jim McCann (David Thewlis), as well as MI6 operative Hamilton McMillan (Christian McKay), who attempts to sign him up for the British secret services.
The whirlwind ride features plenty of humour (of a variety of shades) and also stars Chloë Sevigny as Marks's long-suffering wife Judy, plus Omid Djalili and a cameo from the late director Ken Russell.
