Fourteen-year-old filmmaker Tony Ingram first got permission from Joan Lindsay to adapt her book "Picnic at Hanging Rock" to film as 'The Day of Saint Valentine'. Ingram had filmed only ten minutes of footage before the film rights were optioned to 'Peter Weir', and Ingram's production was permanently shelved. The filmed footage is included on some DVD releases of Weir's film Picnic at Hanging Rock (1975).
The National Film and Sound of Archive of Australia say of the DVD version of this film that this is "the first screen adaption of Joan Lindsay's novel made in 1969 by 13 year old schoolboy, Tony Ingram with commentary by the director".
This unfinished black-and-white 1960s short film version of Joan Lindsay's novel "Picnic at Hanging Rock" is included on certain DVD editions of Picnic at Hanging Rock (1975) and has been also been made available for viewing on the internet.
According to Bernard Hemingway at Cinephilia, "the gem of the extras [included on certain DVD editions of Picnic at Hanging Rock (1975)] is a short film 'The Day Of St. Valentine' which in a striking instance of nascent indie film-making was made by 13 year old Tony Ingram and his friends in 1969 before Lindsay [Joan Lindsay] sold the rights although sadly no explanation of who Ingram is or what became of his interest in film."
Oz Movies says of this film that it is "[director] Anthony S. Ingram's 1969 curiosity, the amateurish 3'44" stab at adapting the ["Picnic at Hanging Rock" by 'Joan Lindsay;'] novel under the title 'The Day of Saint Valentine'."
