I'm not entirely sure, but I don't recall Peter Green being in 'Pulp Fiction'. There are a lot of actors in that movie, but I don't think he's one of them.
Since Peter Green is not an actor in 'Pulp Fiction', there is no role for him to play in it. The movie has its own set of characters and actors who bring the story to life, and Peter Green is not part of that.
In 'Pulp Fiction', the movie is filled with all sorts of interesting characters. However, if we are talking about a 'wolf actor' in a very literal sense, like an actor who is playing a wolf or has a wolf - like role, I don't think there is. But if we consider more metaphorical 'wolf - like' traits in the actions or personalities of the actors' characters, then it's a bit more open to interpretation. For example, some of the characters might be seen as having predatory or sneaky qualities like a wolf, but not an actual 'wolf actor' in the film.
There could be a chance that Peter Donkersloot is a name not directly associated with the main plot of 'Pulp Fiction'. It might be a name of a person who worked on the set in some capacity, such as in the art department or as an assistant to the director. However, without more context, it's really hard to determine his exact role in relation to the movie.
