The San Francisco State University is holding a special advance screening of the first episode of Game of Thrones today, between 6PM and 7PM. First come, first served seating, though they prefer that those attending have an interest in television as an art form. See the Facebook page for more details.
On top of that, the UK’s BAFTA has a free screening on the 15th which sounds particularly interesting, as there’ll be a Q&A with the “creative talent behind the production”. There are limited free tickets available, which you can request via e-mail.
