Quote:
"Gudrun [Bjerring] started off as a cutter, but soon revealed so original a talent for dealing with children and young people that she became a director of such films. She was a very quiet, extremely persistent worker with an outwardly sweet and accommodating approach which masked a truly tremendous tenacity."
