Casting for “Game of Thrones” season 8 is currently ongoing. The producers are reportedly casting a “sassy and attractive” girl and a mercenary, among other new characters. The sets are also being prepared at Northern Ireland. Filming is expected to begin soon.

Since this is the last season of the TV series, no major character is expected to be cast. However, there are plenty of relatively minor roles joining them. According to a report by The Sun, two of these new characters are a “sassy and attractive girl” and a “colourful” young actor to play the role of a sentry. Both are said to be from the North.

The other character reportedly being cast is a mercenary. This appears to be a character of some significance as filming is scheduled to next June for the actor. The length of filming suggests that the role is recurring.

The mercenary has been described as “authoritative, fit, cool and charismatic military type" and will need to be "able to ride a horse." The report speculates that the character will be seen working for Euron Greyjoy (Pilou Asbaek).

Another character the producers are looking to cast is said to be a “rough and ready, sea-faring type" sailor. If these characters are connected to Euron, it looks like he will be back in Westeros, just as Cersei (Lena Headey) has planned.

There are only six episodes in “Game of Thrones” season 8. There’s still a lot of story left for all major characters, and one character expected to return is Tormund (Kristofer Hivju). In a recent interview, cast member Nikolaj Coster-Waldau (Jaime Lannister) said he believes the character is still alive, Winter is Coming reports.
