Two new Israeli actors will be joining the cast of the highly popular TV show, Game of Thrones. The American premium cable and satellite television network, HBO, has decided to bring new additions to the cast of the the network’s highest grossing TV show.

The actors from Israel are Yousuf Sweid, a 39-year old Israeli Arab who is an accomplished film and stage actor, and 33-year-old Ania Bukstein, who emigrated to Israel from the former Soviet Union in the 1990s.

Sweid is no stranger to American premium television productions. He has appeared on the Showtime network drama Homeland opposite Claire Danes and he has a regular role on the FX Network show Tyrant.  Bukstein has previously starred as a lead in the 2007 critically-acclaimed Israeli film, The Secrets (HaSodot), opposite French superstar Fanny Ardant.

Game of Thrones is an American fantasy drama series based on the book series “Song of Ice and Fire” by George R. R. Martin. Since the show premiered on HBO in the United States in 2011, it has become a cultural phenomenon and a commercial success. Drawing in an average of 5 million viewers per episode, it has won 25 Primetime Emmy awards.

The upcoming sixth season is slated to be aired late on April, 2016 and details on the production are under extreme secrecy.

Speculations over which characters the two Israeli actors will be portraying in the upcoming season or even seasons, is ripe on Israeli media. Since the cast and crew of Game of Thrones are under strict confidentiality and non-disclosure contracts, neither of the two actors nor their agents were available for comment on the matter.
