Anyone who could sing 'Bridge Over Troubled Water' with such spiritual clarity must have other talents and so it proved. Harvey Keitel is the actor with the heavier rep but he is often horribly stagey here. Art Garfunkel's performance however, remains authentic and true to life right till the end with an extraordinary level of concentration. He is brilliantly able to show simply thinking, often looking off screen in a state of enigmatic contemplation. It is one of the all time great screen performances and he sadly became an untapped resource in the business.
The constant smoking in the film was rumoured to be an early example of product placement ("thanks, I only smoke these") but the director subsequently denied this, claiming it was meant to dramatise the nervousness of the assortment of neurotic characters. I think it would have been more effective if we hadn't seen what ultimately transpired between the two leads in the film, leaving us to speculate as to whether a line had been crossed into moral horror. This unwillingness to trust the audience and go for the explicit in order to shock is one of the great failings of modern cinema. some commentator at the time described 'Bad Timing' as 'a sick film, made by sick people for sick audiences', but although it's often meretricious, the adults depicted are recognizably that of the real world. It is truthful in many respects. See it as a reminder of the days when British films could be half way decent.
