Note how they stacked the deck, so to speak, with gorgeous lovelies at the pool for this photo below, but didn't bother to ask the paunchy, middle-aged patron in the background to skedaddle out of the shot!
One scene takes place at a competing hotel that overlooks Caesars Palace (again filmed on a soundstage with a cyclorama backdrop) and it hilariously includes a fashion show amidst the cocktails and conversation. A remarkably "mature" model comes around and describes the swimsuit she's wearing, complete with a matching cover-up, and announces that it's for sale at $28.00. (This reportedly used to be a common practice at various restaurants and hotels.)
In between scenes of the screenplay, multiple, brief shots of the card tables and other areas of the place are shown while disembodied voices provide snapshots of dialogue, meant to add a comedic or atmospheric bent to the proceedings. These came courtesy of an improv group called The Committee, who saw a flash of success during the '60s in a couple of troupes across the U.S. and on The Smothers Brothers Comedy Hour among other shows. Their last gig on TV was in about 1974.
