This is an example of what Hollywood was doing, or becoming, in the 60s. Basically television.
The opening scenes of this motion picture were bizarrely generic. A middle aged couple leaves an apartment building for a cab ride to a restaurant all of which plays under the opening credits. It's dialogue-free and the couple turns out to be Dean Martin and a matronly Lana Turner. The silly nothings continue as Dean is interrupted, continually, by phone calls from (his bookie?) and his romantic date, with his wife, goes down the... I don't know this is where I bailed.
Hollywood was trying to squeeze the last drop of revenue from existing resources (sound stages, big name stars and supporting actors, technical and administrative support). I didn't recognize Lana Turner even after she started talking. Never a big fan but aware of her work. The middle-aged Turner was not instantly recognizable, like Joan Crawford or Bette Davis or more recently Jane Fonda or Helen Mirren. This was essentially a domestic sit-com with lies, misapprehensions and bizarre inferences (no doubt) throughout. Supporting cast upholds the resource theory: mostly contract support players from the 40s and 50s.
Post-war Hollywood was teeming with "guys" who could write this stuff, with experience dating back to the 30s, and endless reserves of pretty people who could sell the same old three-act formula ad infinitum, hour-long for dramas, 30 minutes for comedies.
It went on through the 70s before new formats began to emerge in the evolution of what we now call long-form serial entertainment. So this movie? Blech.
