Here's a breakdown of the key elements:
* Cockney: The core of Brick Top's speech is rooted in Cockney, evident in his use of rhyming slang ("apples and pears" for "stairs"), dropping the "h" sound at the beginning of words, and using unique Cockney expressions ("trouble and strife").
* Estuary English: Brick Top's accent also incorporates some features of Estuary English, a more modern and fluid accent prevalent in the southeast of England. This is noticeable in his softened vowel sounds and less exaggerated intonation.
* Birmingham: While less prominent, some listeners have detected a hint of Birmingham dialect in Brick Top's speech, particularly in certain vowel sounds and the use of specific vocabulary.
Ultimately, Brick Top's accent is a blend of these elements, creating a unique and memorable character. It's part of what makes him so iconic and adds to the film's overall authenticity.
