Yes, cars exist in Pulp Fiction. There are several cars shown throughout the movie which are used by the characters for transportation and also play a part in some of the action scenes. For example, the car in which Vincent and Jules drive around is quite prominent.
Sure. There are dining establishments in the movie. The existence of these restaurants adds to the overall atmosphere and realism of the story. They provide places for the characters to meet, have conversations, and often where some of the movie's tension and drama unfolds. One such place, like I mentioned before, is Jack Rabbit Slim's which has a really distinct look and feel.
No. Goku is a character from a fantasy anime world with superpowers like flying and shooting energy blasts. The world of Pulp Fiction is a more realistic (in a crime - noir sense) world. It would be completely out of place for Goku to exist there.
It's highly unlikely that Mario could exist in the world of Pulp Fiction. Mario represents a positive, fun - loving, and somewhat naive character from a video game universe. Pulp Fiction, on the other hand, is set in a dark, dangerous, and morally complex world. The visual and thematic elements of the two are so different. For example, Mario's power - ups like the Super Mushroom and Fire Flower have no place in the world of Pulp Fiction where the power lies in guns and street smarts. Also, Mario's cutesy design and his simple - minded goals would be completely out of sync with the complex, often violent and cynical world of Pulp Fiction.
No. Boba Fett is a character from a science - fiction universe filled with spaceships, alien species, and the like. Pulp Fiction is set in a more down - to - earth (even if highly stylized) world of crime and criminals. The two worlds are so different in terms of technology, environment, and the nature of the characters that it's not possible for Boba Fett to exist within the world of Pulp Fiction as he is.
No. Marge Simpson is a cartoon character from a family - friendly, comical animated world. Pulp Fiction is a violent, adult - oriented and gritty live - action movie world. Their aesthetics, themes and tones are completely different. Marge's presence in the Pulp Fiction world would be completely out of place and break the entire atmosphere of the movie.
