Multiple titles didn't help this turkey

Why is this called "Sharon's Baby" on IMDB when Joan Collins's character was named Lucy? On TCM it was called "The Devil Within Her." On the VHS box shown on the IMDB page it seems to be called "The Monster" and elsewhere, "I Don't Want to be Born."

If this movie was made today, we'd have CGI of a muscular baby scrambling up and down the side of the house and dragging corpses around. Instead we get scenes where it's clearly a doll (Collins tucking an inanimate object into its crib) or a tiny plastic hand shoving an adult into a lake.

Pity Eileen Atkins and "Guest Star" Donald Pleasance, both of whom were apparently desperate for a paycheck in 1975. This half-assed "Rosemary's Baby" ripoff is worth watching at least as far as Collins's inane "erotic" dance which is about as erotic as a Carol Burnett Show sketch. Actually, the extras in the strip club audience should have won awards for managing to look enthralled at all the idiotic acts.
