The film doesn't say for sure if Carmine really exists or not, because that point is not important to the film's story.Ģ. There is no way to determine for sure which one of those possibilities is true, because the film does not provide enough information to make that determination.
Carmine is either a fictional made up person, or a well-known gambler with underworld connections who exists in the film's story (this is still possible even though Carmine is never shown). But to give some more depth in answer to your questions:ġ. The guy timppu quoted has the right idea. I haven't watched the film in many years, but going by the clip that timppu posted, I can infer the answers to your questions.
