Why title 'Brighton Rock' ?
Great film !
The end, when the record is playing was a clever and humorous surprise!
I wondered why was it called "Brighton Rock" ?
I saw no large seaside rock formation in the film.
I had to Google the answer.
I found it at Brighton Rock (novel) - Wikipedia;
"The title is a reference to a confectionery - (rock candy) - traditionally sold at seaside resorts, used as a metaphor for human character."
It looks and feels hard, but if you hit it, it will shatter.
This should be in the Trivia section of this movie.
