This gives us a rough idea of what the plastic knife will cost us so that we can add it to our budget of the rest of the film.
Rock
This will be found in the surrounding location because we do not need to buy a rock to trip up Sam because we will be in a place where there will be various loose rocks on the floor that we will be able to pick up, manoeuvre and place where we want it to be.
Phone
This will be an actual phone that we will just use so that it doesn't look as fake as it would with a teenager walking through the woods not looking at his phone. It adds a sense of realism to the opening sequence because the stereotype of teenagers is that they are always on their phones.
