Lamothe returned to fiction with Équinoxe (1986). When it did not receive the praise he expected, Lamothe returned to documentaries on his favourite theme - North American Indians. La Conquête de l'Amérique I-II (1990-92) emphasizes the claims of the Montagnais and upholds their rights, whereas L'Écho des songes (1993) deals with aboriginal artists from all regions of Canada. In 1996, with Le Silence des fusils, he returned again to fiction by presenting the real story of two Innu who died in a suspicious manner on a river on the North Shore. Taking the side of the Amer-Indian - which a commission of inquiry invalidated in 1998 - Lamothe denounces White justice.
In 1980, Lamothe was the first recipient of the Albert-Tessier Prize. The Native Film and Video Festival honoured him in 1994.
Suggested Screening: Sacré Arthur! (André Desrochers, 1996).
