I have recently started watching Game of Thrones and I noticed that it has many well known actors like Peter Dinklage, Emilia Clarke, Sean Bean, Natalie Dormer and so on.
By famous I mean, actors that are seen in many other movies.
Did these actors really go nude, that is, the bodies we see in the series are their real bodies or have body doubles been used?
I read an article where they explained how they used body double for Lena Headey in the nude penance walk scene of Cersei Lannister. So for other actors (like Emilia Clarke or Natalie Dormer) who are seen naked, was it a real body or just another body double?
