The upcoming season of the popular HBO fantasy drama series "Game of Thrones" is expected to feature some flashback scenes. Season 5 will look back at some of the stories earlier in the lives of several main characters, and it has been revealed the actress who will play the young Cersei Lannister has been cast.

The beautiful blonde and sinister Queen played by actress Lena Headey as an adult will be portrayed by adolescent actress Nell Williams. HBO has not released any official word about the casting, but Williams' agency page has listed "Game of Thrones" as one of her upcoming projects.

Cersei was first introduced in the series as the tormented Queen to King Robert Baratheon. There was no love lost between the two, and it was later revealed that Robert still held his heart for his deceased sweetheart, Lyanna Stark. Meanwhile, Cersei had been keeping an incestuous love affair with her twin brother Jaime with whom she bore three children believed to be Robert's.

In contrast to her love for Jaime, Cersei has a seething hate for her other brother Tyrion whom she blames for the death of their mother. In the books, Cersei had been tormenting Tyrion almost as soon as he was born. It remains to be seen if the upcoming flashbacks will feature scenes between the young Cersei and Tyrion or the beginnings of her love affair with Jaime.

Various parts of the books have recalled other incidents from Cersei's childhood back when she was still living in her family's stronghold in Lannisport. It remains to be seen how many scenes Williams will work on and which other characters will have younger versions of themselves introduced in the cast. Various media outlets have also reported that the adolescent Cersei will be sharing a scene with an older character named Maggy the Frog, who has been mentioned in the books.

Meanwhile, E News has given a rundown of several other new faces that will be introduced in Season 5. With many new scenes taking place in Dorne, more members of the Martell family will finally be introduced. The ruling Lord of Dorne, Doran Martell, will be played by Alexander Siddig and Doran's son Trystane will be played by Toby Sebastian. Prince Oberyn's daughters, the sand snakes, will also be making their first appearances. Nymeria, Tyene and Obara Sand will be played by Jessica Henwick, Rosabell Laurenti Sellers and Keisha Castle-Hughes, respectively. Season 5 of "Game of Thrones" is expected to air this coming spring on HBO.
