Good Lord. The op needs to get some mental health counseling. You are out of your mind.

what's with you people? John Gries has a signature habit that directors/editors are powerless to stop and re-shoot? then he must be the best actor on earth or bullies his way into future movies somehow

I diagree, he doesn't clear his throat, neither he's a bad actor. Here's a short film where he proves his talent:

maybe he has allergies

by - geonet Everytime the guy talks he has to clear his throat.
I can only speak about "The Pretender" and on there he did clear his throat a lot but it was his Character, Broots was always nervous and this helped to show his nervousness and his feelings of inadequacy when speaking or presenting his case, to anyone.. I liked his character, however, and thought he added some great comical moments

ahem

i just wanted to thank you and congratulate you.
This is officially the dumbest post ive ever read. Ever.

I've come to realize that actors who can successfully annoy me with their character's "ticks" or personality traits are, in fact, good actors!
Could he daily feel the stab of hunger for her and find nourishment in the very sight of her?

How can you blame Gries for something the producers or directors of the show could have easily told him to stop doing?
Its part of his character, approved by the people behind the scenes of the show. Deal with it.
"Wolfman's got nards."

Good actor for me, funnyand great in the Pretender !!

I've never seen the movie/show you mentioned with him clearing his throat, but that must have been something he added for the character. Sometimes actors give each of their character's a tick to make them unique.
Unfortunately for you, he must have chosen to have that particular character clearing his throat. In one role, he sniffs things. Another one, he's always tutting. It's normal for someone to have a habit. He's a thoughtful actor to notice that.

I hate it when actors do that "darting iris" thing just before a kiss when in semi-profilelike they are searching for something in the eyes of the persons they are kissing. Supposedly, it's just that their eyes are trying to resist the placement/slow rotation of the camera during the shot. I don't know. I just don't like it.
Makes me want to knee a goat in the teeth.

Yeah! And you know what other action I hate that actors do?blinking. I mean, what's with this continual closing and opening of the eyes? Are they trying to get little nano-second cat naps in, or what? It's like, "Hey! If you're awake, you keep your freaking eyes open, OK? Especially if you're on screen!"

Jon Gries does have one annoying habit he's too damned funny!

Maybe he's got a touch of the plague!

Maybe he has phlegm.

WHAT?
Apparently you have no idea where to draw the line between actor and character. How are you able to judge that Broots' throat-clearing reflects Gries' insecurity as an actor? Broots is an insecure character, so how can you possibly argue that it shows that Gries must be an insecure actor? If you really did understand acting you would understand you have no basis to argue something like that.
And, no, he does not just clear his throat when he doesn't know what else to do. That is just a cop-out and means you don't understand the subtleties of acting. You know absolutely nothing about acting if you think, "To act well, you can't do this." Do not dare to deride Mr. Gries' talent just because his acting was so fully developed that you couldn't understand that acting IS everything you do in the character. If you really think that to effectively act it means you "can't" do some things, then you have a very incomplete idea of what acting really is.

aaaaaaaaaaaaahahahahahahaha! you are ridiculous!

Hey don't dis Lazlo Hollyfield,he'll go Wolf man on your ass and throw a steak at your face.

He completely ruined your watching of the showyet you kept coming back to watch the show.

Only "fuc$#ing morons" can't take a different opinion than their own.

You are (ahem) a (ahem) fuc$#ing moron (ahem).

There is a growing trend of "throat-clearing actors"?!?!
You can't be serious.
Seriously.
WTF?!
Did you read an article in Variety about this growing epidemic of actors who turn to these cheap tricks, like clearing their throat or blinking, or maybe even moving their eyes, instead of the time-tested and "Geonet" approved method of acting?!

Well, okay, I can see where you're going - apparently we just have different perspectives. I respect your opinion as well.
