Supernaturals are a dime a dozen on HBO’s True Blood, but they seem to die off as often as they’re resurrected. To inject some foreign flair into season five, True Blood has cast Italian actress, Valentina Cervi (Miracle at St. Anna) as a fanged regular. In other HBO news, Game of Thrones has cast a major character in their much-anticipated return for season two. Edward Dogliani will appear as the wilding raider known as the Lord of Bones. His character from the George R.R. Martin adaptation will go mano-a-mano with Jon Snow (Kit Harington). Finally, CBS’s Criminal Minds has cast Dean Cain (Lois & Clark) as a villainous gambler for an episode set to air in early 2012. Hit the jump for more on each casting.

The True Blood casting news via THR reports that Cervi will play Salome, an ancient vampire whose seductive beauty, power and intelligence are a force to be reckoned with. She is apparently derived from Princess Salome, the femme fatale daughter of King Herod, the New Testament characterization of dangerous female seductiveness. Look for Cervi and the rest of the True Blood cast when they return in the summer of 2012.

Also from THR comes the news of the Game of Thrones cast addition. Author Martin himself broke the casting news on his blog as he welcomed Dogliani by saying, “I’m looking forward to seeing you in your bone armor.” Dogliani will play Lord of Bones, also known as Rattleshirt due to his armor of clattering bones. He’ll join the rest of the cast when Game of Thrones returns in April 2012.

Finally, THR reported that Superman (aka Dean Cain) will take a villainous turn in an upcoming episode of Criminal Minds. Cain plays Curtis, “a blue-collar, east coast type, down-on-his-luck gambler.” For more on Cain’s character, according to producer Erica Messer: “He thinks he’s found the method to his winning streak and it involves killing people." For shame, Clark. Criminal Minds is currently in production on its 150th episode which guest stars Jay Karnes (The Shield) and Dina Meyer (Starship Troopers). Cain will also appear in an upcoming episode of Burn Notice and a Hallmark Channel’s The Case for Christmas.
