I found the work of Olly Moss a while back when looking at different types of posters, and in terms of minimalist film posters, he's definitely got them down. Ive posted a few examples below which I love. He uses iconic elements or scenes from the films to create some really nice visuals. The black and red designs make me think of some of the old penguin book covers, and the orange ones, the Robocop one for instance, reminds me of the work of Noma Bar, an artist I was recently introduced to. He is able to encapsulate the character in as few lines as possible; the side of the gun doubling as the profile of the face. Very cool.
