I emailed eMovieposter the other day to tell them that, in my opinion, some daybills they had listed as second printings were most likely RRs instead. My thought process was simply because the film (Frankenstein Must Be Destroyed) showed around Australia from 1969 into the mid 1970s and surely it wasn't in cinemas the entire time - hence RR.
Matt from eMovie came back to me to query how I determine the difference. In his view, a RR would have been likely to attract an updated rating (e.g. from SAO to M). Films re-released such as Jaws don't appear to have been re-rated.
I was curious as to what you guys and gals think? Are / were movies re-rated by the OFLC each time they were released back in cinemas?
I get the feeling that there may be no definite answer, but happy to see what people think!
