Someone was responsible for the maps developed for the film adaptations of The Lord of the Rings, The Hobbit and other movies (on-screen and in promotional materials), and that someone is Daniel Reeve, a freelance artist who also did a lot of the letterwork and calligraphy. Via Boing Boing.
A trap street is a fictitious street inserted by a mapmaker to catch plagiarists. Trap Street is also the title of a movie making the rounds of the festival circuit. Directed by Vivian Qu, Trap Street (Shuiyin jie) tells the story of a mapmaker who encounters a mysterious woman on an unmappable street. Based on the IMDB listing, it seems to be headed for a June release. (Does anyone have more information on this film?)
