Xtro (1983) Harry Bromley Davenport

Tony's father Sam, abducted by aliens three years earlier, returns to earth and seeks out his wife and son, but Rachel has since been living with Joe and the reunion is awkward. Joe doesn't trust Sam, and Rachel can't quite decide what her feelings are for her two men. Sam is not the same as when he left, and he begins affecting Tony in frightening ways.

A man is kidnapped by aliens and returns some years later in the form of four legged crablike monster.He rapes a woman and a fully grown human explodes from her womb the next day. "Xtro" is a rather unpleasant low-budget horror gem that is definitely not for the squeamish. The film offers plenty of strange atmosphere and lots of cheap but effective special effects. The gore is suitably nasty and the birth scene is truly disgusting and memorable. The cast is generally decent and the finale is extremely grotesque. Later Bond girl Maryam D'Abo plays the nanny and has a wonderful nude scene.
