Curse of the Fly
This film ends the Vincent Price trilogy of the 1960s. It gives us the tragic conclusion of the story of the Delambres.
It starts off rather odd with a woman in underwear escaping somewhere and, rather than by using exposition, the film takes its time to set up the characters and how she and Martin Delambre fit together. Proving how these films are more drama by today's standards, rather than pure horror.
The experiment with the transporter has made advances. And it even brings them mundane trouble with passports, but sadly it turns out to be their undoing as well. In combination of the sons not willing to continue the family project. Turns out that the woman escaping from the mental institution is the leadt of their concerns.
A worthy conclusion to the trilogy that inspired the great remake by Cronenberg.
