Helmer Denis Villeneuve’s “Polytechnique” nabbed five prizes at Quebec’s Jutra Film Awards Sunday in Montreal, including one for director.

First-time helmer Xavier Dolan’s “I Killed My Mother” won four Jutras, including best film, screenplay (Dolan) and actress (Anne Dorval). It also won the award for the film that had the most success outside Quebec.

The story of an angst-ridden gay teen (Dolan) who has a love-hate relationship with his mother (Dorval) won three prizes at Directors’ Fortnight in Cannes and prizes from both the Toronto and Vancouver film critics circles.

“Polytechnique” is inspired by the mass murder at the Ecole Polytechnique in Montreal in December, 1989. Maxim Gaudette, who plays the killer in the disturbing pic, won the Jutra for supporting actor.

The other big winner was “Dede, a travers les brumes,” the biopic about late Quebec rocker Andre “Dede” Fortin, which also nabbed four prizes, including best actor for actor-singer Sebastien Ricard for his portrayal of the title character.

The ceremony took place at La Tohu in Montreal and was broadcast live on Radio-Canada Television, garnering an audience of just under one million viewers in a province with a population of 7.8 million.
