Looking into other thriller movie posters, I noticed a large proportion use a profile shot/close up of the main protagonists face. We think maybe a profile shot of Esther for our poster could be effective in the same way. There is also an obvious representation of theme colour in all the other thriller movie posters, so for ours this would be blue. Having multiple pictures merged into the one poster looks effective (e.g. for Safe House and Shutter Island). This is something we have taken inspiration from.
