I don't get the importance of the act issue either tbh. I mean, these people are performers, to a greater or smaller degree they put on acts, all of them, that's what they do. Take the unsuspected guy from malta for instance, gianlucca bezzina or something like that, who put on a very convincing act of the very nice guy from next door, teacher's dream, mother's pride. He could actually be evil himself for all we know, he could even be a perverted squirrel rapist if we let our imagination go wild! The point is, artist wise,
it doesn't matter.
Tom whatshisname may very well be the most incredible floor spitting macho in private, or he may dye his beard pink. I wouldn't know or care and I can't imagine why anyone would, unless they were morbid fans of the character.
The whole thing really goes without saying in my view
