Hmmm... nope, CuddlySquig.
Event Horizon is about
Yes, it's vaguely
40k-ish. It might be drawing inspiration from the game we know and love. But then, scriptwriter Philip Eisner is also credited with the script for the Mutant Chronicles movie... And, as many of you know, Mutant Chronicles and
40k share some common ground, to put it kindly
Veerhoeven's Starship Troopers may be inspired by
40k, in both looks and feel. Though the source material predates
40k by four decades, switching the tech-using bugs and power armored mobile infantry for rough equivalents of the Tyranids and the Imperial Guard is intriguing to say the least. Also, the humor: Deliciously over the top while played with a straight face. That's a all over the place in
40k, while completely absent from Heinlein's original.
On a different note, I've just finished reading China Mièville's Embassytown. The means of interstellar travel described in this book bear a striking resemblance to "our" warp: Ships fly through the Immer, a layer of unreality below "the everyday", the material universe. And the Immer is not without its daemons, too. In a scene, an immer-thing of sorts hacks its way into a MIAB, an unmanned cargo ship. When the crews open the ship for inspection, carnage ensues.
But then, a lauded sci-fantasy writer borrowing inspiration from a lowly miniatures game? Naaaah!
