Jean Guilloré, known professionally as John B. Root, is a French director and producer of pornographic films, born on November 28, 1958.

In 1994, as an experiment, he created an interactive pornographic CD-ROM, the first of its kind in France, which was bought and distributed by the French version of Penthouse and met an unexpected success.

[1] He quickly developed in France a reputation as an "intellectual" porn director,[5] and his work was followed positively over the years by cultural magazines such as Les Inrockuptibles[6] and Cahiers du cinéma.

[1] He also attracted media attention by speaking out in favor of "quality porn" and insisting that adult films could be a legitimate art form.

[7] In 1998, he wrote and open letter to the French Ministry of Culture in which he pleaded that porn should receive public funding like other forms of entertainment.

In the course of his career, he has worked with many notable French porn performers, including Liza Del Sierra, Lou Charmelle, Coralie Trinh Thi, Karen Lancaume, Ovidie or Angell Summers.

[2] He has stated that one of his goals is to avoid sexism and misogyny in his films, by not depicting sexual situations that could be perceived as demeaning to women.
