US star Alicia Witt said starring alongside Nicolas Cage in new horror film Longlegs helped with the death of both her parents and a cancer diagnosis.

The actor and singer plays Ruth, the traumatised mother of a young FBI agent, (played by Maika Monroe), who is attempting to bring down the titular killer — played by Cage.
