I’m could care less about his sweater but why do movie producers do this?? They always use shit that is no longer being made or they know people will be forced to pay ridiculous amounts for as far as shoes like please stop that, save peoples bank accounts.
Its not really the producers, its the collectors that buy everything up. In some cases, the people responsible for the wardrobe dept find stuff thats about to be discontinued anyway so its cheaper to buy alot of
I don’t think these movie producers care or keep anything in mind about what collectors will be after post-release, nor would they let that determine costuming. Most often what happens is the items get discontinued after filming, not the other way around.
