    Wrong City

    I'm born and raised in New Orleans. I remember when Jim Giesick and Sam Corey of Texas committed this crime. Corey was a mail order preacher and Texas underworld figure who chose a young girl for Jim to marry and murder to collect the life insurance. While they were on the way to a Florida honeymoon, they stopped in New Orleans where Jim took the girl for a walk and Corey ran over her, making it look like a hit and run accident. My biggest problem with this film is the fact that it's set in Phoenix instead of New Orleans. I don't understand the filmmaker's reasons for this inaccuracy. Would someone make a film about the Civil war and then have it set in Asia?

    Wasted Time...Slow Paced!

    This movie was agony! I tried to give it a chance because I love Patrick Duffy, but this movie was such a slow pace. Too many gaps in the movie. Loses your attention! By the time you piece everything together you realize... It doesn't make a damn lick of sense! Senseless, ridiculous! Unnecessary. Only watch if you have incurable insomnia!

    I was an extra on the movie set

    I'm not sure where the movie was filmed except some of the the court room scenes. They were filmed in downtown Phoenix, AZ in the old courthouse across the street from Maricopa County Superior Court where I worked for 5 years. I took vacation for a week to be on the set as an extra and had a full change of clothes for each day of the courtroom filming. Sometimes, they filmed 2 days in one 8-hour day so it was something of mayhem.

    It was an interesting experience. I was part of the courtroom audience and sat behind Charles Durning who later danced the tango with me in the hallway during a break. Awesome experience! Richard Cox and I discussed the many different dialects for the Southern cultures (he represented a Southern lawyer in the movie) and Michael O'Keefe gave me an autograph but wasn't up for much discussion. Patrick Duffy called me "Sarge" the whole week because I'm a veteran :) Very nice fella.

    I'm thinking parts of the movie were also filmed in New Orleans but I'm not really sure. I watched the movie when it hit the airwaves and walked away from it feeling like they left some vital parts out of the story although I had never read or heard of it as it seemed a bit inconsistent and left me with a lot of questions. Based on the other reviews here, seems like I might benefit from reading the book.

    Jim Giesike

    I also know Jim, I worked with him after he served his time and even though I believe he did his time and is regretful. I was very young when I worked with him and even though I have never been a push over or easily intimidated by others, Jim could achieve it easily, Jim often called my by his murdered wife's name, usually acting as if he didn't know he did it, once my employers wife overheard him calling me Patricia, she informed me that I looked like Patricia. And even though this made me extremely nervous he never acted out of line with me. Jim was always nice to me and taught me much about computers, but there was always a nervous feeling I could not shake when alone with him, a feeling that Jim likes to play psychological games with the people around him, I suspect like many people he likes to see how far he can push, but despite this he always behaved in courteous manner. I knew Jim over 15 years ago, while prison and trying to build a new life with the prison counselor he married was still relatively fresh, he endured a lot and needs to be left alone unless he's breaking the law. We all have demons, some more than others.

    Jim Giesick

    Many years ago I worked with Jim before he married at a Sears store and he was a very pleasant and friendly person.He got along well with others and had a good sense of humor. I was very surprised to hear what happened in New Orleans and hadn't heard any more about the case since that time, I am glad to hear he is out and getting another chance to have a better life.I didn't know that a book was written or a movie was made about him so I can't say one way or the other if it is correct. All we can go by is what we read or hear on the news etc., and sometimes that isn't correct.So you have to draw your own conclusions as to what really transpired. I agree that he has paid his debt to society and wish him the best in the future.
