When the Raven Flies (original Icelandic: Hrafninn flýgur (pronunciationⓘ)) is a 1984 Icelandic-Swedish adventure film written and directed by Hrafn Gunnlaugsson.

[2] Although mainly a tale of personal revenge, When the Raven Flies bears some resemblance to the classic Akira Kurosawa film Yojimbo and A Fistful of Dollars of Sergio Leone, sharing common plot events, characters and action sequences.,[3] which itself drew inspiration from Dashiell Hammett's Red Harvest.

Twenty years later, the boy has become a man and travels to Iceland to seek revenge against the perpetrators and find his sister.

With two of the Viking raiders now living in exile from Norway and king Harald Hairfair, Gestur coldly plays their gangs against each other to get his revenge.

Thord is led to believe that Erik is plotting against him with king Harald and is lying about the Gestur character.

Gestur is secretly wearing armor beneath his cloak which allows him to get in range of Thord and his brother, revealing his true identity and killing them both.

His sister refuses and says that her son is "old enough to have seen too much", using the same words that Thord used twenty years ago when he ordered the killing of Gestur.

Their original plan was to adapt Nobel Prize in Literature-recipient Halldór Laxness' novel Gerpla into a film.

Dutch comics artist Erik Kriek has cited When the Raven Flies as a major inspiration to his graphic novel De Balling (2019), which is also a revenge story set in the Viking Age.
