I always wondered if Kathryn Bigelow is somehow related to Robert Bigelow of Bigelow Airospace. Later has long been the center of a bunch of conspiracy theories.
From wikipedia, after a 5 sec search:
Bigelow was born in San Carlos, California,
the only child of Gertrude Kathryn (née Larson; 1917–1994),
a librarian, and Ronald Elliot Bigelow (1915–1992),
a paint factory manager.
Never heard of the conspiracy theory or Bigelow Aerospace, just about how logic works.
