The worst aspect of this dreadful movie for me was the sound. As a former sound engineer, the displayed incompetence made my skin crawl.
In the wedding scene at the start of the movie, the wedding singer, despite standing right in front of a microphone, is all but inaudible. Same goes for her instrumentalists. I thought I was listening to a badly folded down 5.1 mix before I realised the sound recordist just didn't seem to know what he was doing: in the courtroom scene when the protagonists are walking through the halls of the courthouse, the sound is reverberant, indirect and muddy: the conversation outside the court between James Brolin and Tatum O'Neal is notable because the picture cuts between the two characters are audible; you can hear the traffic noise in the background changing suddenly with each one.
There has been very little if any post production audio dubbing done on this movie. The entire soundtrack would serve as a guide track in a dubbing suite but it's a disgrace as the finished product.
In the middle of the movie, without warning and apropo nothing at all, the director decides to regale us with a reprise of a large number of scenes taken from the first half of the film, cut together and shown mute with a pointless overdub of some syrupy vocal ballad. It was at that point that I gave up watching this amateurish tripe. One or two reviewers of have applauded Brent Huff for his direction in this film. Personally, I wouldn't let him direct traffic if Last Will is an example of his skillset.
Oh, and Tatum O'Neal can't act to save herself.
