"...Rule #1: Actor has to be alive (unless playing a zombie or vampire)..."

Here! You can't go slapping on rules like that at this stage of the game!

Perhaps after this thread breake the 100 (or 150) barrier, it might be possible to produce a 'practical' list (all actors alive as they are today) and an 'ideal' list (any, alive or dead at their prime or the appropriate age).

How about the late Charles Grey (the crimanologist in 'Rocky Horror Picture Show') as Dr. Downey ?
