Props

Last year for my AS opening of a film I made an alien hand for my prop. This year as I am creating a trailer I didn't want to give it away too much that my film is about aliens so I will not be showing any alien footage. I only want to suggest aliens but leave it to interpretation as it taser my audience more and that is the idea be hide teaser trailers. But I will be using fake blood to suggest elements of horror in my film and also to grab my target audience's attention.
