Travels With My Aunt (1972)

In the lively comedy/adventure Travels with My Aunt, adapted from Graham Green's book, Henry (Alec McCowan), a timid, bookish accountant whose life seems to have died stillborn, discovers how to live with gusto thanks to the rough ministrations of his thoroughly eccentric aunt Augusta (Maggie Smith). Aunt Augusta bursts into Henry's life during the funeral for his mother, Augusta's sister. She whisks him to her apartment for a general cheering up, and he is thoroughly bemused by her bohemian ways and her much-younger black Caribbean boyfriend. In the next few hours, she manages to pry him from his dusty life and involve him in a series of incredible adventures involving old love affairs, espionage, kidnappings, and more money than he has ever dreamt of. Before the story ends, Henry has properly gotten into the spirit of his madcap aunt's adventuring.
