Ok, I'm going to go on a small rant regarding these clue seekers who are so myopic in their focus they can't tell a product placement from a clue.
First, Slusho is a product. Yes, it appeared in Alias. Yes, it's logo is seen on someone's t-shirt in the Cloverfield trailer . But does this make it a clue? Hell no!
The definition of a Clue is "Something that serves to guide or direct in the solution of a problem or mystery."
So how does a website called Slusho lead is to the solution of the mystery of what this film's about? Answer? It doesn't.
It's a way of Slusho benefiting from this viral marketing campaign. Period. Indeed, they may have paid a fee for this or at the least provided cast and crew with tons of Slusho drinks on the set.
But that's it.
