Jedidiah states that the woman in the photo "has dancers legs" and much is made of that statement by Barnaby Jones; but in the close-up on her photo, it can clearly be seen that her legs are shapeless and flabby, show cellulite and therefore do not resemble the muscular legs that dancers typically have, so there was no reason for Jedidiah to speak that superfluous line. Either the actress ought to have been replaced to match the script, or the line ought to have been removed so as not to look bizarrely incongruous.
At about 41 minutes, Jim Rhodes is assembling a revolver with a silencer. There's no way to silence a revolver since the bang also comes out of the front of the cylinder. Clearly a bad prop gun.
