After a four-year absence , Claude Miller returned to active filmmaking with '' The Accompanist '' ( 1992 ) and '' Le Sourire '' ( 1994 ) . He had to wait until 1998 for his next major success : '' La Classe de Neige , '' the chilling story of a lonely boy on a school skiing holiday , which won the Jury Prize at the 1998 Cannes Film Festival . Later films Miller directed include '' Betty Fisher et autres histoires '' ( 2001 ) which Peter Bradshaw wrote that Miller " endowed it with the fascination of an exotic , spiky , poisonous flower " , '' La Petite Lili '' ( 2003 ) , and '' A Secret '' ( 2007 ) . At the time of his death he was working on an adaptation of François Mauriac 's '' Thérèse Desqueyroux '' . The film was selected to close the 2012 Cannes Film Festival
