Shirley Anne Field gives a fiery performance as a young designer on the brink of starting an affair with a married male supervisor (Robert Stephens) at the wallpaper factory where she works. Based on the play by acclaimed writer John Mortimer (Rumpole of the Bailey), Lunch Hour is directed by James Hill (Black Beauty, Born Free). With its tightly-focused plot and real-time narrative this stylish examination of an illicit lunch-hour rendezvous features an underlying sexual radicalism that tells us much about the time in which it was made.
