Oficialmente, o show é "strongmente inspirado no filme". Mas há muitas conexões entre as duas linhas da história, a maleta incluída. Aqui está uma lista mais exaustiva de conexões (spoilers): link
Sobre a pasta de dinheiro, especificamente, no link acima:
The briefcase: Having killed Jean’s father and taken the briefcase full of $1 million in ransom money, Carl pulls out the agreed-upon $80k that he will share with Gaear. He buries the rest in the snow on the side of a desolate road along a fence, using his red ice scraper as a marker so he remembers where the money is located. Broke and desperate, Milos flees to Minnesota with his family in 1987 – except along the way, he runs out of gas. His car just happens to stall out at the exact spot where Carl buried his briefcase full of money. Milos spies the ice scraper, digs, and finds the treasure. The scene firmly plants the series within the same universe as the film.
