In her autobiography, Doris Day wrote: "Of all the people I performed with, I got to know Cary Grant least of all. He is a completely private person, totally reserved, and there is no way into him. Our relationship on That Touch of Mink (1962) was amicable but devoid of give-and-take...Not that he wasn't friendly and polite - he certainly was. But distant. Very distant. But very professional - maybe the most professional, exacting actor I ever worked with. In the scenes we played, he concerned himself with every little detail: clothes, sets, production values, the works. Cary even got involved in helping to choose the kind of mink I was slated to wear in the film."
When Cary Grant noticed an ad for a raincoat that he thought would be appropriate for Doris Day to wear in the picture, he called the owner of the company who made it. After explaining who he was and what he wanted the coat for, he was given the brush-off by the manufacturer, Norman Zeiler, who later recalled that he didn't believe it was Grant. "So I told him if he wanted to see our collection, he'd have to come up himself. And he did." The much-imitated Grant, who usually made all his own calls and answered his home phone himself, often had that problem. People just couldn't believe it was really Cary Grant they were talking to.
Cary Grant was a big fan of The Honeymooners (1955) and Audrey Meadows in particular, and was responsible for getting her the part of Connie.
Audrey Meadows' housekeeper, Pat Scofield, desperately wanted to meet Cary Grant. She would sit in Meadows' dressing room waiting for an opportunity, asking the actress's make-up man and hairdresser to fix her up in case Grant came her way. One day Meadows told Grant about Scofield, and he asked to meet her. According to Meadows, the housekeeper handled herself very well during the encounter but nearly collapsed when he left the room.
Shayne discounts the New York Yankees, joking that they "try hard." Ironically, the movie was filmed in 1961 - the year the Yankees would win the World Series in five games, and Roger Maris broke Babe Ruth's home run record. As this film was released the following year, the audience was delighted.
