Josh Zammit says he has always been a filmmaker at heart, even from a very young age. He made home videos when he was 13 then upgraded to short movies when he was 16. After high school, he enrolled in a screen and media course at The Northern Sydney Institute's film and television school at St Leonards Campus.

Now 24, Josh's first feature-length film, Observance, has burst onto the overseas film circuit and has been gathering positive reviews in both Europe and North America. The Hollywood Reporter has described the film as "one of the most chilling experiences" while Cinapse has labelled it "a cult classic".

Produced with a budget of just $11,000 and filmed entirely in less than a fortnight, Observance tells the story of a private investigator who is paid to surreptitiously film a woman at her home from an abandoned apartment in the building next door. Tension builds as the investigator starts to notice some disturbing developments in the woman's life.

Josh is surprised at the positive attention his film has received as he admits Observance "wasn't going to be everyone's cup of tea. It's an ambiguous thing we've done. We were expecting some hate."

Observance will have its Australian premier at the Randwick Ritz in Sydney on Sunday 3 April, followed by a limited theatrical run nationally.
