'House of Cards' Welcomes Back 'Game of Thrones' With Taunting Tweet
Game of Thrones' fourth-season premiere Sunday night was welcomed with a challenge from House of Cards.
The Netflix series' Twitter account capitalized on the interest around its fellow beloved series and HBO rival by tweeting a photo of Kevin Spacey's Frank Underwood sitting on an iron throne accompanied by the caption, "Long live the king." The tweet also read, "May the best House win."
