Deadline reported that Andersen was cast as a series regular, playing the older version of Ragnar and Aslaug\'s youngest son, Ivar the Boneless. As fans know, Ivar -- who was born with twisted and seemingly broken legs -- is more dangerous than he appears. In fact, earlier in the season, Ivar struck one his playmates in the head using his hatchet after he was ignored by him.

Andersen\'s TV credits include "Outsider," "Tvillingerne & Julemanden" and "Hedensted High."

Smith plays Ubbe, the firstborn son of Ragnar and Aslaug. Ubbe has proven his sharpness and assertiveness earlier in the season when he was able to track Floki (Gustaf Skarsgård) through the wilderness and cunning enough to spot him in the water.

Smith is known for his roles on the Australian soap opera "Neighbors" and on British drama series "Banished." On the film side, the Scottish-Australian actor recently appeared in Angelina Jolie-directed war film "Unbroken."

Ilsø is Hvitserk, Ragnar and Aslaug\'s second child. He and Ubbe joined the Northmen in their second trip Paris. According to the saga "Tale of Ragnar\'s Sons," Hvitserk inherited Jutland (Danish mainland) and Wendland (Luchow-Dannenberg in Lower Saxony) after the death of his father.

Ilsø appeared in the Danish series "Mikkel og guldkortet" and starred in films "The Model," "The Absent One" and "Danny\'s Doomsday," among many others.

Lastly, Lindström plays Sigurd, the second to the youngest son of Ragnar and Aslaug, who also goes by the moniker Snake-in-the-Eye. In early episodes of the current season, Sigurd was shown to be an intelligent child who witnessed the effect a returning Harbard (Kevin Durand) has over his mother and the other female folk of Kattegatt.

Lindström portrayed Simon Nilsson on the Swedish political drama series "Blue Eyes."

The quartet makes their debut appearance in tonight\'s mid-season 4 finale of "Vikings," which confirms the much speculated time jump on the series.
