A key film of the British New Wave, Saturday Night And Sunday Morning was a great box-office success - audiences were thrilled by its anti-establishment energy, the gritty realism of its setting, and most of all by a working-class hero of a fresh and outspoken kind. Based on Alan Sillitoe's largely autobiographical novel, the film is set in the grim industrial streets and factories of Nottingham, where Arthur Seaton spends his days at a factory bench, his Saturday evenings in the local pubs, and his Saturday nights with Brenda (Rachel Roberts), wife of a fellow factory worker.
Played by Albert Finney with an irresistable animal vitality, Arthur is anti-authority ("Don't let the **** grind you down") and unashamedly amoral ("What I'm out for is a good time. All the rest is propoganda"). With powerful central performances, cracking dialogue by Sillitoe and a superb jazz score by Johnny Dankworth, Saturday Night And Sunday Morning still stands as a vibrant modern classic.
