A number of you have already responded to my query about the human voice; thank you. One response I got was the following: Hi Kristine, In _Soylent Green_ (1973, Richard Fleischer), Edward G. Robinson has a death scene (it was his last role, ironically) in which he reveals crucial information to Charlton Heston's character, who listens via a headphone, but there's a little static interference, and so we never get to hear what is actually said : the information is only revealed later ("Soylent Green is People!"). Needless to say, this technique of withholding information to create intrigue is very widespread, and I'm sure you can find a zillion examples in classical Hollywood films... Hope this helps! There ARE a zillion examples in classical Hollywood films, in all probability, and it does seem like the point is to create suspense -- a sound enigma, as it were. What, if any, are other motivations for this kind of interference, do you think? ---- To signoff SCREEN-L, e-mail [log in to unmask] and put SIGNOFF SCREEN-L in the message. Problems?
