Everybody seems to be following everyone in this caper from Bogdanovich. Some really big names: Audrey Hepburn, Ben Gazzara, and of course, 33 year old John Ritter, while he was still making Three's Company. Minimal speaking, at least the first part of the film. Turns out, private-eyes are following spouses who may be playing around. Some pretty good singing by Colleen Camp, who plays the jealous Christy. Great street scenes of New York city. Patti Hansen (now MRS. Keith Richards in real life! ) is taxi driver Sam, who pals around with Russo (Gazzara). although everyone is pretty much hitting on everyone in this tangled bowl of spaghetti. lots of following people around the streets of new york. Bogdanovich explores married people flirting and fooling around. and partners and new friends keep meeting the other partners. Bogdanovich really explores un-expected new relationships, and people having multiple partners. Why does Christy keep saying Charles?? quite odd. and "Jose" is Hepburn's real-life son. lots of similarities to What's Up Doc, but that was just one person trying to steal the engaged guy away from his fiancee. As goofed up as director Bogdanovch's personal life was, he sure made some great films. My personal favorite is What's Up Doc? really interesting info him on wikipedia, as well as a full interview in New York Magazine March 2019. Good character study.
