Note on authorship
'Mrs. Betty Davis, the young Melbourne playwright who achieved fame at a bound a few months ago with "The Touch of Silk," an intensely human little play, has now achieved the further honour of being one of the first women to write an Australian talkie. Just now at the Palace Theatre in this city two talkies entirely Australian made are being seen and heard and one of them, "Spur of the Moment", is by Mrs. Betty Davis.'
