At the time The Brood was developed, Cronenberg fought for custody of his daughter from his first marriage. This was the first film scored by composer Howard Shore. Shore has written the music for all but one of Cronenberg's subsequent films.
A meningioma is a type of tumor that develops from the meninges, the membrane that surrounds the brain and spinal cord. There are three layers of meninges, called the dura mater, arachnoid and pia mater.
An unusual appearance for meningioma, called meningioma-en-plaque, has a flattened appearance that conforms to the curves of the brain and the inside of the skull. Meningiomas represent the second most common type of tumor of the brain, accounting for approximately 20% of all primary intracranial tumors in adults.
