While I Live is a 1947 British drama film directed and co-written by John Harlow and starring Sonia Dresdel, Tom Walls and Carol Raye.
[2] While I Live is best remembered for its musical theme "The Dream of Olwen" composed by Charles Williams, reprised at intervals throughout the film, which became hugely popular in its time and is still regularly performed.
Driven to complete the piece by her domineering elder sister Julia (Sonia Dresdel), Olwen becomes agitated and despondent, and one night sleepwalks to the edge of a cliff near their home.
On the 25th anniversary of Olwen's death, Julia is listening to the broadcast when she hears a frantic knocking at the door and opens it to admit an unknown young woman (Carol Raye), who immediately walks up to the piano and begins expertly playing along with the piece on the radio.
A local faith healer, Nehemiah (Tom Walls), who also claims second sight, becomes involved and it seems increasingly as though history is repeating itself, culminating when the young woman too is found standing precariously on the edge of the cliff from which Olwen fell.
