Hoffman (1970)

Synopsis
A woman who is blackmailed by her boss discovers his plans are not at all what she imagined in this low-key comedy-drama. Benjamin Hoffman (Peter Sellers) is a businessman who has eyes for a secretary working in his office, Janet Smith (Sinead Cusack). Smith is engaged to marry a man named Tom Mitchell (Jeremy Bulloch), but when Hoffman learns that Mitchell has a criminal past and is wanted by the law, he makes a startling proposal to Smith -- he'll turn her fiancé in to the police unless she agrees to spend the weekend with him. Smith sees little choice but to agree, but arrives at Hoffman's door imagining the worst. However, to her surprise she discovers Hoffman is a desperately lonely man who wants to be loved, and he demands almost nothing of her but her companionship. ~ Mark Deming, All Movie Guide
