The films of Quentin Tarantino use a number of fake products and for good reason. From Reservoir Dogs to Once Upon a Time… in Hollywood, the films of the legendary writer/director are known for their graphic violence, fast-paced dialogue, and imaginative world-building. This world-building often includes original brands, such as Big Kahuna Burger or the Le Gamaar Cinema, from Inglourious Basterds, that don't exist in real life.
