Initial Planning - Ideas for Props

There are only a few props needed for consistent use throughout my film trailer. Examples of props I shall use throughout the duration of my film trailer include: 

A selection of props that are essential to the protagonist's identity.

This could include a pair of glasses, a wig or a piece of distinguishable clothing (e.g. a bright red jacket). These props must be key to the protagonists appearance as the audience will pick up on different aspects to her image (such as the fact that she wears glasses) continuously throughout the start of the trailer where the focus shall be on her. My intent is for the antagonistic character to steal the girl's identity towards the end of the narrative, so I would have to use props that are specific to her own appearance. I plan on the scene showing the stalker stealing her identity to appear ambiguous to the audience; instead of revealing the antagonist's full identity, I shall include footage of them picking up certain items and then placing it onto themselves (e.g. a close up of the antagonist raising a pair of the protagonist's glasses to their face). Although I have not yet chosen the cast for my film, a wig could be useful if the protagonist is clearly shown to have a different hair colour to her stalker, therefore allowing the audience to assume that the antagonist would have to possess the same qualities as the protagonist to make her appearance seem more convincing. I could experiment with using different saturations of light within the scene to allow the audience to focus on particular (brightly coloured) pieces of clothing.
At least one prop that is essential to the protagonists identity shall be featured in the film. However, this particular prop will be finalised when I come to planning my protagonist's costume, when I have a clearer idea of how she will appear onscreen visually.
