Bit of a silly one...
Watching a tv drama and wondering how easy is it to play a corpse? How is it actually done? Just lay still, no blinking etc.. I couldn't do it. I know it's probably done in takes so the actor doesn't need to stay still for long, but even so.
In autopsy scenes, I'm assuming its usually a dummy as skin is shown with incisions etc.
I know I'm naive but I'm generally interested.
