Daughter of the Mind

1969's "Daughter of the Mind" is a creepy, plodding supernatural thriller starring Ray Milland as a scientist who becomes convinced that he can communicate with the spirit of his deceased little girl. The film boasts a great cast including Gene Tierney (in her final film role), Don Murray, John Carradine, and Ed Asner. Tragically it's never been issued on VHS or DVD... but it has shown up online.
