It's Not A Spoiler, It's In The Title: John Dies At The End Trailer
It's also got a pretty wicked trailer, and no, I don't totally understand it, or the header image, but I like them both regardless. The film's synopsis doesn't really help unravel the bizarre narrative and meta-textual (the main character is also named David Wong) twists and turns, either:
It's a drug that promises an out-of-body experience with each hit. On the street they call it Soy Sauce, and users drift across time and dimensions. But some who come back are no longer human. Suddenly a silent otherworldly invasion is underway, and mankind needs a hero. What it gets instead is John and David, a pair of college dropouts who can barely hold down jobs. Can these two stop the oncoming horror in time to save humanity? No. No, they can't.
Here's the trailer:
I can reconcile the Stephenson-meets-Lovecraft synopsis with the Fear and Loathing in Las Vegas by way of Gilliam trailer, but I'm still not sure what that was, other than radass. It felt like a Cracked article come to life, and I mean that in the only way possible: the best way.
