​​​​​Gunnar Grimmson is a supporting antagonist in the 2018 Film Fantastic Beasts: The Crimes of Grindelwald. He is portrayed by Icelandic actor Ingvar Eggert Sigurðsson.


Grimmson was a wizard-bounty hunter, who was notably employed by the British Ministry of Magic over the years. At some point he got in a rivalry with Newt Scamander.

Around 1927, he was hired by the Ministry of Magic in order to assasinate Credence Barebone, after Newt Scamander had turned down the task to capture the young man. Newt showed clearly disgust over this decision. Secretly he was though working for Gellert Grindelwald, and on the dark lord's orders, he received orders to kill Irma Dugard, to deprive Credence of the answers he was seeking and to push him into Grindelwald's arms.

He later met Grindelwald in the sewers of Paris, in which the dark lord promised that the bounty hounter would be remembered as a hero in history for his services.


  • Possibly Icelandic, based on his name and the nationalty of the actor.
