Season 5 of HBO’s acclaimed adaptation of the epic series by George RR Martin ends on Sunday, June 14, and fans will have to wait until 2016 for an update on their very favorite (and most loathed) characters. With its enormous cast and numerous storylines, Game of Thrones has launched the careers of several young actors, including Sophie Turner, Maisie Williams, and Kit Harington. But before they struggled and sparred in Westeros, many Game of Thrones stars appeared in some of Britain’s most popular television series.

Starting June 15, check out Acorn TV’s Before the Throne playlist for the full list of stars and shows.

And if you love the bloody intrigue of GoT, don’t miss Britain’s Bloodiest Dynasty: The Plantagents. Premiering June 15, this riveting documentary was hailed as a “gleeful…exploration of intrigue, betrayal, and beheadings” (The Guardian, UK).

Out of the chaos, darkness, and violence of the Middle Ages, one family seizes control of England, holding onto power and ruthlessly crushing all competition for more than 300 years. They are the Plantagenets. Through dramatic reenactments, historical documents, and masterful storytelling, Britain’s Bloodiest Dynasty: The Plantagenets tells a tale more shocking and more brutal than anything you’ll find in fiction.
