11. Costumes
When a noob actor starts out in regional theater performances, it’s normal to furnish parts or the whole of one’s wardrobe. Hollywood spends big money on wardrobes, but when they filmed Bewitched, the supporting actors would often provide their own costumes. They would bring in clothing a week before filming. The wardrobe would clean and press their clothes, then make them available for the episode. At the end of the day, they could go home in their costumes. That’s one way to save on production costs.
