The World of Henry Orient is a 1964 comedy film directed by George Roy Hill. Peter Sellers plays a concert pianist named Henry Orient, who is having an affair with a married woman played by Paula Prentiss while two preteen boarding-school girls played by Tippy Walker and Merrie Spaeth stalk Orient and write their fantasies in a diary. Much of the humor of the film derives from Orient's paranoia that the two girls, who seem to pop up everywhere he goes, are spies sent by the husband of his mistress. When Walker's mother, played by Angela Lansbury, finds their diary, she suspects that Henry has acted inappropriately with her daughter. Tom Bosley has a supporting role as the husband of Lansbury.
