MORTEM, directed and co-written (with Marie-Claude Dazun) by Eric Atlan, and which I originally viewed during a Film Comment Selects series back in 2012.
Did I ask why? Well, for the hot lesbian sex scene that grounds the middle of the movie, of course.
Daughters of Darkness onwards.
The Artist and the more recent Blancanieves, this movie has been filmed in that exciting new process known as black-and-white cinematography (by M. Atlan himself, and the photography is indeed quite beautiful). In fact, for those who love crisp, clear and gorgeous variations of black, white and gray, the movie is worth seeing for these alone.
