Particularly relevant for the Mort people (this means laurenmitchell, mstakenidentity, hespa, sols_light, possibly impostinator, pearl, aurellia, and others who I may have forgotten or may not read this because I'm not on their friends lists :-) ).
Last night (well, in the early hours of this morning), I asked Stephen Briggs if he had any advice for a bunch of people putting on Mort .
His advice :
1. Learn the lines.
2. Don't use scenery.
3. Have fun.
(and 4. Use a battery-powered fan to keep Death cool, if the costume is hot/bulky).
Terry chipped in saying that Death's face should either be a good mask or greasepaint (i.e. not a cheap plastic skull-type mask).
Wheeeee ! Enjoy :-)
