For a poster I made recently I used Cardo a free Google Web Font. It needs very little modding to look exactly like this logo. It read somewhere that the actual font used is one of Adobes many pro fonts and costs an arm and a leg. IMHO go with this.
EDIT: I rushed into my answer, sorry my Cardo suggestion is in reference to the 'Game of Thrones' text and not the text that is used in the poster, if anyone wants to recreate the logo style then Cardo.

It worked I use it, w/o problems!

I know I'm late, but I was able to identify it. It's Eva Antiqua SG Heavy.

The N's left leg is different unfortunately, other than that it looks identical to me.
I also found another close match, OPTIEve Heavy, but in this case it's the N's right leg to be different.
