The World of Henry Orient (1964) review

Two mischievous girls who are big into music, Val (Tippy Walker) and Gil (Merrie Spaeth), spot "famed" pianist Henry Orient (Peter Sellers) having a snog in Central Park with a married woman (Paula Prentiss) and then Val becomes infatuated with him (even making a scrapbook detailing her love) and chase him around the city (to the dismay of their parents).  The antics of the girls are supposed to be "cute" and "quirky," but I found them to be irritating and creepy, and the movie itself is a little disjointed: the attempts at humor stop in the last third when it shifts to family drama, and Val goes from living in fantasy land to cold reality, when she sees with her own eyes Mommy being intimate with someone who isn't Daddy (in what's a particularly vicious role for Angela Lansbury).  I'm not sure why Sellers keeps changing his voice throughout, but one fun piece of trivia is that his "New York accent" is modeled after none other than Stanley Kubrick.
