They're real! No shit!....apart from one.
Tombstone - the Kevin Jarre western from 1993 featuring Kurt Russell as Wyatt Earp and Val Kilmer as Doc Holliday and the events leading up to the gunfight at the OK Coral - features some of the finest Hollywood mo's I've ever witnessed. It was on TV last night at the pub, and the landlady put it to me that none of the 'taches on display were real: "Take it from me Jordy, I used to be a hairdresser. I know a fake when I see it."
Evidently not.
I've checked a few sources online, in particular this one with Michael "Johnny Ringo" Biehn, stating that Kevin Jarre insisted the stars grow their own moustaches in particular styles with waxed curly up ends. Only one actor, Jon "Sheriff John Behan" Tenney sported a falsey apparently due to time constrained by his previous role.
That's crackin'! This is no crusade to prove landlady Vicks wrong - I simply love the fact that all (most of) that facial hair was self cultivated.
Isn't that a daisy?!
