A discussion the other night about movie taglines reminded me of my favorite one. The film Howard the Duck was a terrible failure, one of the great failures of movie history as I understand it. However, the ads were great. There was the duck on the poster, poking his head through something and looking freaked, and the tagline was "Trapped in a world he never made."
Which was enough of an in-joke that I'm sure they didn't care at that point who didn't get it; the movie was already tanked.
Who remembers why they used that? And can quote the source? Hm? ;)
