Haraldur has been a part of the Icelandic performance arts scene for quite some time. Before he graduated from the Royal Central School of Speech and Drama in 2015 he appeared in various music videos, feature films, short films, and was one of the founders of a devising theatre company. He was also a member of the pop band Retro Stefson which was a very popular band in Iceland. They toured all over the world and ended up moving to Berlin after they signed with Vertigo (Universal music) in Germany.

After graduation from RCSSD Haraldur moved back to Iceland where he was offered a position in the Reykjavík City Theatre. He has been with them since then as well as acting in a few Icelandic feature films and TV-series.

Most recent work: Gunnar (one of the main antagonists) in Trapped 3 (Entrapped) and Einar in Katla. Both available on Netflix.
