NOTES: A handy Hoyts performer considering its competent, but hardly A-list cast. But a handful of bookings it was a top-biller and had an even spread between Saturdays and Tuesdays. Rarely strayed far from the city and the Independent chain showed little interest in playing it. Siren of Atlantis was its regular support partner.
