I remembered how Event Horizon (one of my favourite movies, seriously) is often called a Warhammer 40 000 prequel. So what works can you think of that could fit / be interpreted in as happening in Warhammer 40 000 universe, especially if they are interpreted as dealing with Chaos?
I would nominate Event Horizon (Gothic looking ship which tests what is supposed to be teleportation drive but ends up shifting vessel tohyperspace Hell / Chaos) and Outpost (a 2008 film about a bunch of mercenaries who look for a piece of Nazi mad science and end up finding ghost soldiers created by said pece of Nazi mad science).
