Mostly on the basis of how much ear shows below the wig,
The interesting thing, and the one that on-and-off makes me go 'ehhhhh', is that the Guy, in the Dauntless shot (yes, you got it right), is wearing what looks like the wig Gillette wears in the dock scene. I don't think it's just camera angle.

But seriously, that dude is not Gillette. And the earlobe thing is a very good point, as is the wig-fitting.
