The property master is responsible for selecting parts of the set and costumes. This includes large items like furniture and vehicles, but also small items like tools and weapons. When you see a mother cooking breakfast for her kids, the prop master has chosen the stove, the frying pan, the plates, and almost everything else in the scene. For a prop master, details are everything. In the 2011 movie The Social Network, the prop master had to find the exact model of computer that Facebook founder Mark Zuckerberg used when he was studying at Harvard University back in 2004. Part of the job is also keeping track of every item purchased for the movie and making sure no item disappears during production.
