Because the raw CLT numbers give the wrong impression, I wanted to establish the common name for costume supervisor Barbara Siebert Bolticoff. She's in the database with multiple name variants.

- IMDb
- AllMovie

INVALID (2 confirmed):

These are both "Costumer" credits, which doesn't qualify for inclusion per the crew credits table.

Note that there's an additional Barbara Siebert acting credit in German series 'Spuk von Draußen' - this is a different person, and that credit should therefore not be taken into account here.
