‘Doctor Who’ series 9 trailer has a ‘Game of Thrones’ twist

Two fan cultures collide in the new “Doctor Who� trailer that was dropped at Comic Con 2015.

The Comic-Con crowd was treated to a first-look glimpse of “Game of Thrones� actress Maisie Williams -- who plays Arya Stark in the George R.R. Martin epic fantasy in BBC’s brand-new trailer for “Doctor Who.�

The British sci-fi adventure series, which celebrated its 50th anniversary in 2013, returned last fall for its ninth season since rebooting. The show is centered on a time-traveling alien known as the Doctor, currently portrayed by Peter Capaldi, and his traveling companions, the latest of whom is played by Jenna Coleman.

The actual role was not a surprise, and was announced months ago, but images of her in the role had not been released. Williams also isn’t the first “Thrones� actor to appear on “Doctor Who,� as more than 20 actors have appeared on both shows. Among them Mark Gatiss (who plays Tycho Nestoris in “Thrones�), Paul Kaye (Thoros of Myr), Ron Donachie (Rodrick Cassel), Liam Cunningham (Ser Davos Seaworth), Tobias Menzies (Edmure Tully), Thomas Brodie-Sangster (Jojen Reed) and Iain Glen (Jorah Mormont).

David Bradley, who plays Walder Frey in “Thrones,� played a ruthless villain in an episode of “Doctor Who� and portrayed William Hartnell (the first actor to play the Doctor) in the 2013 docudrama “An Adventure in Space and Time.�
