Contrary to documentation widely available on the internet, research by John Broadley has revealed that the architect was not Douglas Smith, but was in fact George Newton Kenworthy, a prominent Sydney architect who had done extensive theatre design. One of his better-known surviving works is the Cremorne Orpheum.
ARCHITECT’S WORK. TENDERS ACCEPTED. Mudgee – Erection of picture theatre –G. N. Kenworthy, architect; A. C. Eden, 100 Benaroon Road, Belmore, builder. (Construction and Real Estate Journal, NSW, Wednesday, 3rd April 1935, p. 10)
Kenworthy is an important factor to consider regarding Mudgee's Regent Theatre. He was involved extensively with the State Theatre in Market Street, Sydney’s most lavish theatre of all time.
