The new cast member Eric Winter looks taller than Alex O'loughlin and Eric is said to be 6'1". Alex O'loughlin was slouching in the scene but it looked like Eric had easy height over him.

In the first episode of Moonlight the actor who portrays the professor is listed as 6'2", there are two scenes were Alex O'loughlin and this actor come face to face it is very clear that Alex is an inch or more shorter.

He looks shorter because of his big frame but he's 6-1 if not taller.

In The Shield looks this.186-87

He seems to be fairly tall in moonlight but he is always wearing huge biker boots. I would say he is 6'1".

Katie says on 16/Jan/08
His frame makes him seem shorter, but he is at least 6'1 if not 6'2.

I have serious doubts that he's that tall...with Justin Chatwin he has looked a little bit shorter then this mark - well, about 6'0.25" but then, again, Justin has been in huge boots during the most part of the "Invisible", so...
