I'm going to be putting on Hamlet in a little over a month and we've been trying to think of a way to make the ghost seem to float across stage. The director has specifically told me that this effect needs to look real, if it looks cheesy he's going to cut it and do the scene with a voice-over. I was thinking blacklights and finding some fabric that really starts radiating, but I'm not sure how it's going to look. Does anybody have any suggestions for making a realistic looking ghost?? Any input would be much appreciated!
