What would the theme be for a movie?

The summary must be good.. The movie should contain a message to the viewers.. You said its for the school assignment, so it will get more noticed only, if you can add a good moral message to the viewers.. It can be anything like helping mentality, love, sympathy, good attitude, friendship, against corruption/ drugs... Such moral things gives you good applause from the viewer's side... Hope you got what you needed.. Good luck with that.. :-)
