Opal Dream (also known as Pobby and Dingan) is a 2006 Australian drama film, based on the 2000 Ben Rice novella Pobby and Dingan, directed by Peter Cattaneo and starring an ensemble cast including Vince Colosimo, Jacqueline McKenzie, Christian Byers and Sapphire Boyce.
The film begins by introducing Kellyanne Williamson, playing with imaginary friends Pobby and Dingan.
Ashmol, while he loves his sister, is frequently annoyed when she talks to her imaginary friends, and some of the kids at school tease the siblings because of them.
Kellyanne is grief-stricken at the loss of her imaginary friends and takes ill, although doctors can find nothing physically wrong with her.
Convinced that Kellyanne is faking her illness, Ashmol nonetheless goes along with her wish that he try to find Pobby and Dingan.
This cut was made against the wishes of the director and crew but did air uncut and as originally intended when shown on BBC Two in 2008.
The website's critics consensus reads: "Earnest performances and Peter Cattaneo's sympathetic direction gives heart to the simple, timeworn script.
