In the latest video update Henry has a different face than previously, and Daniel Vávra confirmed in the youtube comments that it is in fact a face of an actor who will play Henry in the final game. Vávra has commented on casting process quite a lot on his facebook page and he has mentioned that they have found a perfect actor for the role (he never named him), but they had some problems with scheduling and Vávra then never said whether they made a deal with that particular actor or not. It was supposed to be a semi-famous british actor known from some popular british TV series. Can someone recognize the actor based on the 3d model of his face? It is possible that in the end they hired someone else, but in case it is the actor Vávra was talking about, it should be possible for people who know him from TV to recognize him.
