I just got an email from world-renowned trailer maker Mark Woollen, about a new initiative he's launched that could very well change the way film previews are consumed. It's called the "i-Trailer," and it allows a user to experience dozens of rich-media hot spots by clicking specific points on the screen. The new service launched this week, with a trailer for Sex and the City 2. While I wish there was a more enticing film to play over and over, the i-Trailer function is a handy way to get information on plot points (the new man who pops up unexpectedly) as well as locations or merchandise in the film (Carrie's clothes). Plus, Woollen tells me that "there's lots of cool features we've developed for video, commentary tracks, tickets purchasing etc. that aren't in this first one." Mark Woollen is a genius, and this is just more evidence. Try it out by clicking here.
