One of the well - known Easter eggs is the briefcase. It has a mysterious glow when opened, and it's a big part of the film's intrigue. Also, the use of the same actors in different roles throughout Tarantino's movies can be considered an Easter egg. For example, Samuel L. Jackson appears in many of his works. Another one could be the references to other movies and pop culture, like the dance scene which has a unique style inspired by different cultural elements.
The soundtrack in Pulp Fiction is full of Easter eggs. Tarantino often uses music to create a certain mood and also as a form of homage. For instance, the song 'Misirlou' at the beginning sets the tone for the whole movie. The dialogue is also filled with Easter eggs. The characters' conversations are littered with references to other movies, TV shows, and cultural phenomena. The gold watch that Butch has is also an Easter egg. It has a story behind it that ties in with the themes of loyalty and family in the movie.
