For Actors

Realistically

Mainly up and comers, I like the idea of giving people their start. Plus with horror type movies, big names are a plus, but not the most important. As in horror does well with or without them.

Ideally and for Cameos

As for cameos or named actors, I don't have any particular person in mind.

Though I think having someone either in the role of Andrea or in one of minor roles like Gregor, Cathrine, Alec, or The Tall Man.
