Props and costumes

We are going to need several props for our film, these are going to include a football (this will be very easy to obtain as many of the male actors will have at least one we could use), many empty beer cans/bottles to use to represent a drunken teen scene. We want our actors to wear casual clothing so they can move easily and comfortably, also it would be more authentic if they were to wear the clothes that they would normally wear.
