Michiel Huisman has secured a series regular role for "Game of Thrones" season 5 even before the fourth season airs. The "Nashville" actor, who was initially booked for a multi-episode arc in season 4, has reportedly signed up to return as a full-fledged series regular should the show get picked up for a fifth season, AceShowbiz said.

Huisman was quietly cast to replace Ed Skrein to play Daario Naharis, the new love interest to Daenerys' (Emilia Clarke). The character was first introduced in season 3 as Dany conquered two of three great Slaver Cities of Slaver's Bay across the Narrow Sea, Astapor and Yunkai, before heading to Westeros.

Huisman had a role on "Treme" as drug-addicted musician Sonny and still stars on "Nashville" as bad-boy music producer Liam McGuinnis.

Premiere date for season 4 of "GOT" has not been announced but it's expected to air sometime in spring. Meanwhile, the season 3 DVD is going to be released February 18. Kings Langley, a historic town just 20 miles northwest of London, is going to be renamed King's Landing in anticipation of the DVD release.
