Karen Gillan wears a wig or hair extensions. She shaved off her famous red locks for the film Guardians of the Galaxy (2014), and still had short hair in March when filming scenes for the pilot.
The author of the article about Korean men being comfortable kissing is Matt Smith, which is also the name of the actor that played the 11th Doctor on the popular show Doctor Who, which also starred Karen Gillan as Amy Pond from 2010-2012.
To promote the series, ABC released the pilot on Video on Demand and online streaming services on August 20, 2014 - several weeks before its "official" premiere on September 30, 2014. Between the promotional premiere and the official premiere, many changes were made, including almost completely writing out the character of Ethan, played by Tim Peper who left the series after the pilot.
The pilot episode was uploaded on Twitter on August 20th 2014, a month before the show's television premiere in the United States.
