Trailers seem to be getting longer and longer. Far from teasing the audience and igniting curiousity, they show a concentrated version of the movie and reveal practically everything.
The trailer for Gulliver's Travels goes on for bloody ages and pissed off countless people over the Christmas period waiting....waiting....waiting for the main feature to begin. It is a shining example of the new breed of preview. The film itself only runs for 85 minutes (probably 8 of those minutes are credits) - meaning the trailer is 1/34th of the film or essentially 3% of it. However, it seems to contain every moment of note. It's unclear whether there is anything worthwhile in the other 82 minutes but judging from reviews probably not.
