You're a movie marketer in your big-shot's office in LA. It's hot, you've had way too much coffee and your client wants to know your plan to publicise their latest blockbuster.
You haven't got one. So you come up with the idea of a trailer teaser, a 20-second hint of what's to come in, er, the trailer. This situation seems the only credible way to explain the half-a-minute sneak-peek of Len Wiseman's remake of Total Recall, which has been released online as a sort of amuse bouche to its trailer, which comes out on Sunday.
Still, as irritating as it is, at least it is more illuminating than the Twilight trailer teaser, which lasted all of 12 seconds.
