Actors, props and costume

We have asked two b-tec drama students to star in our film. Emma is good friends with these two Girls and they said that they would be happy to be in our film whenever we need them. we have chosen to drama students as we hope that they will be profesional and take our film seriously. also to make it look effective we need actors that know what they are doing and can take insrtruction and we believe these girls can do that.
The Main props we need are a pack of tablets, this is to show that she has an illness and we also need a knife which we have go from emmas house were our opening is set. we are also thinking of using oatmeal to put in the girls hair when she is sick because we think it might look real and effective.
we are thinking that the girl should be quite gothic looking, as the streotypical scizaphrenic person is gothic and we got our inspiration off the character Newt from hollyoaks.she will be dressed in long black clothes and black makeup so she looks strange and different from other people. Our imaginary friend will be dressed in a white gown as if she looks like she came out of a mental home. It will be muddy and a bit ripped to show that she doesn't care what she looks like. She will have bare feet and her hare will be covering her face to show she isn't right in the head.
