Game of Thrones season 7 will begin filming in September this year but the production has already begun for the new season. Gwendoline Christie (Brienne) and Iain Glen (Jorah) were also spotted in Belfast this week.

As you can see in the above tweet, Glen was also reading a script but Game of Thrones cast last week told reporters at Comic Con that they are yet to receive scripts for season 7. Watchers on the Wall reckons that both Glen and Christie are probably there for costume fittings and the script was probably for some other project.
