I Killed My Mother (2009)

French Canadian filmmaker Xavier Dolan stars in his directorial debut, a semi-autobiographical comedy drama about the bonds between mother and son. Surly 16-year-old Hubert lives in suburban Montreal with his single mother Chantale. He doesn't make life easy for her, loudly contradicting or objecting to virtually everything she says or does; understandably, in return, she barely pays attention to his constant negative barrage. But she only starts to realise quite how far they've drifted apart when she discovers, via another mother, that Hubert is gay and going out with his schoolmate Antonin.
