Voici pourquoi :
* Origines : Cary Grant was born in Bristol, England, and his original accent was a standard British English accent.
* Influence hollywoodienne : Il a déménagé à Hollywood dans les années 1930 et l'industrie cinématographique de l'époque encourageait souvent les acteurs à adopter un accent plus neutre, à consonance américaine. This was partly due to the desire to reach a wider audience and to avoid regional stereotypes.
* Mélange unique : Grant's transatlantic accent was a unique blend of his British roots with a cultivated American intonation and pronunciation. It was smoother and less regional than either standard American or British English.
It's important to note that the transatlantic accent was popular in Hollywood during the Golden Age of Cinema. It was a distinctive feature of many famous actors and actresses of the time.
Ainsi, même si l'accent de Cary Grant était en fin de compte un mélange de ses origines et des exigences de sa carrière, il est souvent classé comme un accent transatlantique.
