Well, I'm sure he was working around the limitation that it was his first movie and it was going to have almost no budget.

According to IMDB trivia, they didn't even have a wardrobe budget. All scenes before they wear black suits, the actors were asked to bring their own clothes. And the black suits were provided for free.

That was actually Michael Madsen's own car.

They kinda had to do some gorilla filmmaking. Buscemi's scene where he takes the car was done when there were no cars at that intersection. And I believe I had heard that Buscemi and the cops chasing after him on that sidewalk, they simply ran around real people that were on that sidewalk.

Seeing as though he was going to film it originally without any professional actors, Tarantino already had to make the script be as budget-friendly as possible. Once the script got in the hands of Harvey Keitel, he helped raise a little money and brought in actual actors.

I remember finally watching the movie on DVD about 20 years ago, that the audio in the movie appeared to be of higher quality than the visual aspect of the film. Seems like they wisely spent what small budget they had on that.

I'm always fascinated with movies that you can tell the premise and setting of the movie is based entirely on the fact that its low budget and they're trying to shoot in as few locations as possible. I remember watching a trailer recently for a movie in which everything takes place in a warehouse because its a photo shoot. And the photographer, assistants, make-up artists, and models are all having conversations with one another in the same area. The more I forgot that the movie is filmed in one area, the more impressive it is.
