I Killed My Mother (French: J'ai tué ma mère) is a 2009 Canadian drama film written, directed, produced by and starring Xavier Dolan, in his directorial debut.

Loosely autobiographical, it follows the complicated relationship between a young man Hubert Minel (Dolan) and his mother (Anne Dorval).

The film begins with Hubert Minel giving a black-and-white monologue explaining how he loves his mother but cannot stand being her son; he also reveals that when he was younger, things were better between them.

The relationship between mother and son continues to deteriorate, and Hubert goes to live with his teacher, pretending to be staying with his boyfriend.

The school's principal calls Chantale to inform her of the developments, revealing the note Hubert left, saying he will be "In his kingdom".

The principal also begins to lecture Chantale, which causes her to have an angry outburst at him, saying how he thinks he's better than her and how he has no right to judge a single mother.

[2] Dolan said that the system to acquire funding is "[...] an obsolete financing mechanism that holds the creative assets of Quebec hostage.
