Quentin Tarantino refuses to help his mother financially, after she mocked his writing ambitions.
Although the 58-year-old writer and director is now one of Hollywood's biggest names, he is still bitter that his mother Connie - who turns 75 next month - did not support his writing dreams and he vowed at the age of 12 never to share his fortune with her.
Tarantino is estimated to be worth US$120 million (NZ$171m).
Speaking on The Moment podcast, which is hosted by Billions co-creator Brian Koppelman, Tarantino recalled his mother siding with his teachers after he got in trouble for writing screenplays at school.
