: Step into the world of Henry Orient...and meet two junior-size misses and one king-size nut!

Decked out with another of his American accents, Peter Sellers plays self-centered concert pianist Henry Orient. While Henry's active libido sends him off on pursuit of married woman Paula Prentiss, a pair of preteen boarding-school chums, played by Tippy Walker and Merrie Spaeth, worship Orient from afar. The girls' overworked imaginations, manifested in pursuing Orient about and recording their fantasies in their diaries, leads Walker's mom, Angela Lansbury, to conclude that Henry has "had his way" with her underaged daughter. The World of Henry Orient was later musicalized for Broadway as Henry, Sweet Henry.

Concert pianist Henry Orient (Peter Sellers) pursues an affair with a married woman, Stella Dunnworthy (Paula Prentiss), while two teenage private-school girls, Valerie Boyd (Tippy Walker) and Marian Gilbert (Merrie Spaeth), stalk him and write their fantasies about him in a diary.

Orient's paranoia leads him to believe that the two girls, who seem to pop up everywhere he goes, are spies sent by his would-be mistress's husband. When Val's mother, Isabel Boyd (Angela Lansbury), finds their diary, she suspects that Henry has acted inappropriately with her daughter. She contacts Orient and they end up having an affair. Val finds out about it, as does her dad (Tom Bosley). There is an unhappy ending for Val's parents' marriage, but Val and her dad start to develop a much closer relationship.

The World of Henry Orient was the official U.S. entry at the 1964 Cannes Film Festival.[2][3]
