Here's what these 20 stars were doing before 'Game of Thrones'

"Game of Thrones" has been a launching pad for a number of stars.

While some actors, such as Peter Dinklage (Tyrion), had established careers, some, such as Kit Harrington (Jon Snow), were virtually unknown.

Harrington had only worked in theater before he auditioned for - and booked - his first TV role as the beloved Jon Snow. Maisie Williams and Sophie Turner, who play his sisters Arya and Sansa Stark respectively, had never acted professionally before.

The show and its actors have been nominated for numerous awards, including a Golden Globe and two Emmy wins for Dinklage.
