Directed by Mark Egerton and starring Gary Day, the film's story bears a resemblance to Rear Window.

Ed Ballinger is an engineer who uses a wheelchair and is developing a computer system with artificial intelligence called the I-500.

He received from development money from the New South Wales Film Corporation and wrote early drafts with the assistance of Byron Kennedy.

Then Ross Matthews became involved as producer, and the NSWFC agreed to finance the entire movie themselves under the title Wall to Wall...[2] Just before filming commenced Ross Matthews got another film funded, Hoodwink (1981) and so brought in Errol Sullivan as co-producer.

Vincent Monton’s glossy photography and the assurance with which director Mark Egerton frames each shot make Crosstalk a film of great visual flair.
