The show reportedly just cast Sam's entire family.
First reported by "Game of Thrones" fan site, "Watchers on the Wall," James Faulkner, Samantha Spiro, and Rebecca Benson will play Sam's father, Randyll Tarly; mother, Melessa Florent, and sister, Talla Tarly, respectively.
They join "Unreal" star Freddie Stroma, who was cast earlier this month as Sam's brother, Dickon Tarly.

In addition to a successful career in theater, Spiro's credits include the films "From Hell" and "Beyond Bedlam." She also starred on the popular British series "Psychobitches," "Grandma's House," and "M.I.T.: Murder Investigation Team."
Benson is fairly new to the business, judging from her IMDB profile. She graduated from the Royal Scottish Academy of Music and Drama in 2011. She went on to appear in a few shortlived TV series and the films "Macbeth" and "Tonight You're Mine."
The last time we saw Sam, he left The Wall and Jon Snow (Kit Harington) then headed off to Oldtown to become a new "maester of the wall."
An HBO representative was unable to confirm the castings for Business Insider.
"Game of Thrones" will return to HBO in Spring 2016.
