MEDRA = DREAM ??
Whenever i see an odd name I always look for an anagram -- in this case medra could be dream -- but except for the girls going into a dreamlike trance I can't think of any reason for it. Have to admit it is an odd name even for an alien.
Those who read the book might be able to offer an explanation maybe??
Kind of liked the movie - has it's moments - but in the end the critiques posted here by others are certainly valid -- a British "Mars Needs Women" except it is Ganymede. All the usual questions remain unanswered at the end of the movie. A Quatermass wannabe for sure.
I'm just another sucker for 50s British sci-fi!!
