The Last Wave (Black Rain, U.S. title) was released in 1977 and was directed by Peter Weir. I won't spoil the plot if you haven't seen it (it IS well worth seeing, a short review can be found at this link). However, this being a sewer blog, this must be reported! A sewer in Sydney, Australia, gets featured as a gateway to a subterranean otherworldly place. The capture below simply does not do it justice, it's a pretty cool sewer. See it for yourself!
