Milk is a colloidal mixture of water, lipids, carbohydrates and proteins.
When you heat this mixture, evaporation goes on and the upper layer of milk gets supersaturated, high temperature denatures milk proteins and the colloid collapses.
The "film" hence is a layer of clotted proteins and long chain carbohydrates, interpenetrated and fused by milk fats

Wow! Whatever Mary L said. I learned something new today. Oh and my contribution... because hot chocolate gets a skin, and it's made of milk... therefore, I have proven by induction that milk must have a skin.

the top layer evaporates easily - why do you think babies that are fed only on milk still have plenty of poos! it goes quite solid once it evaporates, hence why it is easy to turn into yogurt and cheese!
