Each director is represented by my favorite film of them.
Directors who aren't on letterboxd, their approximate placement and the would-be film in the list:
#180 CANADA (Luis Cerveró & Lope Serrano & Nicolás Méndez) -- El Guincho - Bombay
#190 THOMAS RIDGEWELL -- Asdfmovie3 (2010)
Some films aren't listed, in which case I picked the next-best thing. See notes for the real favorite film.
Some films are efforts by co-directors. In some cases those directors are just pretty much an inseparable package, in others only one director is meant to be highlighted, in which case, again, refer to the notes.
