Crossword clue: Film

The answer "COAT" fits the crossword clue "Film" because a coat can refer to a layer of something, like paint or varnish. When you apply a coat of paint, it creates a film over the surface. Additionally, in some contexts, a coat can also mean a protective covering, similar to how a film protects an object. This connection between layers and protection makes "COAT" a clever answer for the clue.
