Why is it important when Vincent opens the briefcase in Pulp Fiction?

In Pulp Fiction, when Vincent opens the briefcase, a golden glow emanates from it. The contents are not fully shown but it gives off an otherworldly and important feel. It's one of the most iconic and mysterious moments in the movie.

I have no idea. It's a mystery that the movie doesn't clearly reveal.

It was a sudden turn of events. Maybe it was just bad luck or a consequence of the dangerous world he was in.

Maybe it was to add depth to the story or show a certain aspect of his character.

Well, that's a tough one. The contents of the briefcase and why it was cracked are never explicitly revealed. It could be anything from valuable jewels to something more symbolic or abstract that's up to us to interpret.

Nobody really knows for sure. It's one of those mysteries left up to the viewer's imagination.

Vincent dies towards the end of the movie when Butch accidentally shoots him.

It's kind of a random turn of events. Maybe it was just his unlucky day.

There are several reasons. One could be the dangerous and unpredictable nature of the criminal world they were in. Another might be the series of events that led to that fateful moment. It was kind of a culmination of everything going wrong.

He died because of a series of unlucky events and mistakes. He was in the wrong place at the wrong time and got caught up in a dangerous situation.
