How disappointing that no one has been able to identify the movie, it looks intriguing.
Here’s another one: I saw this one around 1980 on French CBC- some foreign looking horror, there was a young woman (kinda looked like Mia Farrow from "Rosemary’s Baby") in a mansion study, and there was an older woman (some witch I'd gather?) looking on and a dude who was trying to get the filly to hop in his Bentley and go for a ride, the young woman denied and he left, then she knelt down on the floor and exposed her back, which started getting these creepy cracks (like the ‘spider web’ thing that happens to the skins of characters from the first "Evil Dead", dig?) then the cracks widened and her back caved in… and if that wasn’t bad enough- a small, bizarre, mutant baby stepped out of her innards. cut to exterior, day: So the man gets in his car and starts to drive off, while he’s speeding across the countryside he checks the rearview mirror and sees the horrible abomination staring back at him, the little fiend lunges at his face and starts mauling it (not unlike the picture from my first post), then they crash… that’s all I recall, anyone know this one?? I thought forever that it was "The Brood", but after watching "The Brood" realized it was not, the great French horror "Baby Blood" has a similar scene at its climax.
