During production, no. Everything is kept separate. The props and wardrobe needs would be coordinated by the same person, but they (usually the first AD or somebody in their department) would coordinate what piece needed to be where and when.110% on board with you seth
Seth I have a question for you, in all your experience have you ever seen a wardrobe depart keep props with the costume?
example. If Hamill’s costume goes in the wardrobe would the lightsaber go with it?
just had a wonder today about it.. nothing really the helps me theorizing just a general question
But AFTER a project has wrapped it is possible. Rented stuff goes back, studio owned stuff is returned to lock up, custom made stuff might stay with the prop team, or the studio might claim it, people could walk off with it, or it could go into storage if the studio felt there was a chance of it being re-used. In the case of Lucasfilm, they have their own archives as we all know, and EVERYTHING goes into it. They do so much promotional and museum tour work they definitely pair props with costumes (sometimes legit, sometimes copies as we've seen.)
So it could certainly happen once a movie is wrapped.
