I'll try and create the scene...
The American astronauts go into this crater - completely dark of course, and for some reason they have this flashing strobe light (don't torches work on the moon?) and regularly light their path. Lots of grunting and panting as they make their way down into the crater and then "pop" goes strobe and the full screen shows the Cosmonauts skull. Shock value - but I did feel a sphincter loosen a little.
Noyade has control 
Thanks mate, but I can't accept that on the grounds I watch B-grade horror.
NOT a challenge, just out of interest for anyone. Recognise any of the interiors? Quiz from the mid-90's...
OPEN HOUSE.
