Snapshot released in the US as The Day After Halloween and One More Minute is a 1979 Australian thriller film. It was the first feature directed by Simon Wincer.
Ginnane had originally intended to make a film after Patrick called Centrefold, based on a script by Chris Fitchett, and raised money for it. He showed it to TV director Simon Wincer who only liked the fact the script was set in the modelling world and there was a Mr Whippy Van. Ginnane then commissioned Everett de Roche to write a new screenplay. Wincer says he and de Roche rewrote it in three weeks, and the film took eleven weeks from the first day of shooting until sitting down with the release print.Wincer planned to use a different actress to play Angela but she turned it down because she did not think the script was good enough which was pretty amazing for someone who had only done television soap operas. Sigrid Thornton was cast two days before shooting started. ........
