Arnas Fedaravicius is a Lithuanian actor and producer known for his role as Sihtric in the British historical fiction series, The Last Kingdom.

Studying at the Lithuanian Academy of Music and Theatre, Fedaravicius was on the fast track to the screen, also receiving intensive stunt training, which was soon to become useful for his fight scenes in the popular period piece.

With credited acting roles in productions including Deadly Code (2013), Chasing Solace (2015) and Access All Areas (2017), Fedaravicius became more visible with the portrayal of Andrus in the television drama series Thicker Than Water. Appearing in several roles over the series duration, something bigger was waiting ahead.

The release of its first episodes in late 2015 captured an audience beyond borders, but The Last Kingdom was far from its peak. Co-produced by Netflix, where the show now airs, the series soon cast Fedaravicius in the of Sihtric, a character whose story is far deeper than the eye can see.
