Who has sharp brows, anyway?

Character description from 'Candida', a play by George Bernard Shaw:

"He has a healthy complexion, a good forehead, with the brows somewhat blunt, and the eyes bright and eager, a mouth resolute, but not particularly well cut, and a substantial nose, with the mobile, spreading nostrils of the dramatic orator, but, like all his features, void of subtlety."

I can't help thinking the auditions for the first production must have dragged on a bit.

'Yes, thank you, we'll let you know. Well… what did you think, Mr Shaw?'

'Hmm. Not bad. His brows were blunt enough, and his mouth was just the right amount not particularly well cut. But... I'm not sure about his nostrils…'

'Really? I thought he had the most mobile, spreading nostrils we've seen.'

'Oh, I agree. But I'm just not sure they were void of subtlety.'

'Yes, they definitely were…'

'I'm afraid not. I think his nostrils were a tiny bit subtle. And I believe I've made it clear how important it is to me that all his features be void of subtlety.'

'Yes. Yes, you have. Next!'
