Though I knew there were some DVD copies around, I guess I should thank YouTube for finally being able to watch this movie since that's where I discovered it. Having seen it, I can see why Warner Brothers sued and won their lawsuit against American International for blatantly copying WB's hit The Exorcist. Sure, the differences are that one involved a girl child and the other a grown woman but they both have shaking furniture and demonic possession in which they both say very vulgar things involving sex. Okay, with that out of the way, let me say what I think of it. I thought it was hilarious whenever the title character played by Carol Speed had-through the voice of Bob Holt-said all those blatantly provocative remarks to various people but after that, I managed to also find some genuine scares and thrills. Both Ms. Speed and William Marshall as Bishop Garnet Williams who tries to get the demon out of her provide great presence in their scenes together. But the supporting players of Terry Carter (Rev. Emmett Williams, Abby's husband and Garnet's son), Austin Stoker (Abby's brother Det. Cass Potter), and especially Juanita Moore (Miranda "Momma" Potter) also hold their own against them. If there's one thing I have a beef with, it's the print I watched. Perhaps because of that lawsuit, no one's bothered to restore it. So the one I saw looked washed out. Still, the sound wasn't bad so that's a plus. Really, all I'll say now is if you get the chance to watch Abby, go for it! P.S. How interesting that after not sharing a scene in The Mack, Ms. Speed and Ms. Moore played daughter and mother in this. And nice to hear Carol's writing and singing skills with the song "My Soul is a Witness".
