Thanks. I am humbled. I hate Cary Grant though. Hes not an actor. He is a movie star.

It were 1930s, everyone talked like that back then in the movies.
It is zeitgeist.
The distinctive speaking style used in Hollywood films of the 1930s is known as the Mid-Atlantic accent or Transatlantic accent.
This was an artificial, consciously learned accent that blended features of American English and British Received Pronunciation. It was not a naturally occurring regional dialect but rather a cultivated affectation taught in elite American preparatory schools and acting academies.
Key characteristics of this accent included:
A non-rhotic pronunciation, where the "r" sound was often dropped at the end of words or before consonants.
Softer vowels, with words like "dance" or "ask" being pronounced with a broader "ah" sound ("dahnce", "ahsk").
Clear, sometimes clipped, enunciation, partly a carryover from the stage where actors needed to be heard in large theaters before modern microphone technology improved.
The accent was adopted by actors like Katharine Hepburn and Cary Grant, and it was thought to convey sophistication, education, and an elevated social status to a broad audience.
