When photographer Billie Mason (Louise Currie) and journalist Jeff Carter (Wallace Ford) are leaving for Dr. Brewster's (Bela Lugosi) house, Billie jokingly calls Jeff "Mr. Brisbane". In the banter, she was referring to Arthur Brisbane (1864-1936), who was known as the greatest newspaper journalist of his time.
