The clearest mental leap is that minor entities "grabbed onto the Event Horizon" during its increasingly short trip in the warp. The comment on how Chaos entities would act isn't accurate as the books and I do read everything I can from black library act in many differing ways. One that I personally subscribed to and the similarly is huge.

Isner is just admitting he may have subconsciously borrowed (stolen?) the idea of faster than light travel intersecting with a hell-like dimension. There's no "official link" to Warhammer 40K from Event Horizon.

However, the question mentions if Event Horizon is a "prequel" or "Has there been any official attempt to link the movie into the game's universe?". Much later edit: There's a later added answer that mentions that Isner found it to be an influence. Personally I always felt the plot of Event Horizon seemed close to the plot of Doom. And the suggestion that one's interstellar starship can get demonically invaded while traveling faster than light.

Therefore this sounds like an unsubstantiated rumor based on the similarity of the warp drive in Event Horizon to the " warp" in WH4K. I can find no real link between Paramount and Games Workshop nor between the Event Horizon writers and the Warhammer 40K writers. Event Horizon was written by Philip Eisner and Andrew Kevin Walker and was distributed by Paramount Pictures.
