If you've ever wanted to see a live-action Half-Life 2 movie, these mock posters are only going to make you want to see one a lot more.
They're the work of British graphic designer Sean Keenan, and are, for the most part, wonderfully tasteful and subdued.
He's based them on the posters for Chris Nolan's The Dark Knight Batman movie, if you think the colour palettes and design are familiar.
