Back in October, we reported that the hit HBO series Game of Thrones will employ its first flashback, which will be the opening sequence of the Season 5 Premiere. Today we have more details about the flashback, which will feature Nell Williams as a young Cersei Lannister. Both the actress' IMDB page and her talent agency resume confirms the casting, with Watchers on the Wall reporting that the scene revolves around young Cersei and a friend of hers visiting an older woman known as Maggy the Frog.

It's worth noting that Nell Williams' IMDB page has her listed in the first three episodes of Season 6, not Season 5, although that could be a simple clerical error. HBO has already renewed the show for Season 6, but it seems unlikely that she has been cast for this season, since production hasn't even started yet. However, if she has been cast in the first three episodes of Season 5, it could signify there will be even more flashbacks this year. Our October report revealed that there will only be one flashback scene in Season 5, but perhaps that has changed.

Watchers on the Wall also reports that another young actress, Hattie Gotobed (Jack the Giant Slayer, Snow White and the Huntsman) has been cast as a character named Ghita, although no further details were revealed. HBO still hasn't issued a premiere date for Season 5 at this time, but hopefully we'll hear more about these upcoming episodes in the near future.
