The first part of the design was using faces of the three main actors, cropped and grayscaled. Then, they were copied and masked, so the image on the bottom could be transparent and blurred.
A lighthouse was a major location, so it was the centrepiece of the poster. Yellow light from the lighthouse peirces through the grey fog, a mix of low opacitiy, blurred and smudged greys.
The logo was made out of multiple colours for strong contrast, red chosen for the murder mystery theme. The top left corner is faded to match the name, and there’s light blurs to continue with the
foggy theme.
The rest of the text also follows this colouring scheme, and when turned into an ad, the company logos were moved to the lighthouse and everything was condesned together.
