Aromatheatre

Has anyone ever used smells in theatre?

The answer must be yes, I would have thought, as it's pretty obvious and I shouldn't have thought it's that technically difficult; but it's not something I've ever come across (beyond 'flavoured' liquid for smoke machines).

I was in the Oxford Playhouse the other week in the fourth row, being pelted by their keenly efficient ventilation system. It was like being blown incessantly be a small petulant child. Not very nice. But it did make me think: with air circulating that well, if an actor were laced with some kind of scent, every time they came onto the stage they would waft out over the stalls and stimulate the assemblage in their olfactory regions.

Is that a thought worth investigating?
