In the world of 'Pulp Fiction', the name Chris Brayshaw doesn't ring a bell as a major character. However, it could potentially be a crew member, or someone involved in a very niche part of the film's creation. Maybe it's a name that has been misremembered or misattributed. It could also be that in a particular director's cut or extended version that was only shown in a limited capacity, there was a reference to this Chris Brayshaw, but in the general public's view of the movie, it's not a known entity.
There's no well - known character named Chris Brayshaw in the classic 'Pulp Fiction' movie. It could be that this is a name from a fan theory, an extra in the filming that someone is particularly interested in, or perhaps a name associated with some sort of behind - the - scenes aspect that isn't widely known. Without more context, it's hard to say exactly who this is in relation to the movie.
