Beowulf & Grendel is a 2005 film Canadian-Icelandic fantasy adventure film directed by Sturla Gunnarsson, loosely based on the Anglo-Saxon epic poem "Beowulf".
 It stars Gerard Butler as Beowulf, Stellan Skarsgård as Hrothgar, Ingvar Eggert Sigurðsson as Grendel and Sarah Polley as the witch Selma.
 The screenplay was written by Andrew Rai Berzins.
 The soundtrack was composed by Hilmar Örn Hilmarsson.
 While some of the film remains true to the original poem, other plot elements deviate from the original poem: three new characters, Grendel's father, the witch Selma, and Grendel's son are introduced, and several related plot points were developed specifically for the film.
The final act of the Anglo-Saxon poem "Beowulf" is about the hero Beowulf's fight with a dragon, the third monster he encounters in the epic.
 On his return from Heorot, where he killed Grendel and Grendel's mother, Beowulf becomes king of the Geats and rules peacefully for fifty winters until a slave awakens and angers a dragon by stealing a jewelled cup from its lair in order to gain freedom from killing his brother.
 When the angry dragon mercilessly burns the Geats' homes and lands, Beowulf decides to fight and kill the monster personally.
 He and his thanes climb to the dragon's lair where, upon seeing the beast, the thanes flee in terror, leaving only Wiglaf to battle at Beowulf's side.
 When the dragon wounds Beowulf fatally, Wiglaf slays it.
Varela was born and grew up in Södermalm on the south side of Stockholm.
 Both parents are from Spain and he did not learn proper Swedish until he started school.
 During middle school a new friend was Gustaf Skarsgård, son of internationally noted Swedish actor Stellan Skarsgård.
 Varela did not then know of the famous Skarsgård family because he mostly watched Spanish satellite television.
 When his friend Skarsgård applied to a selective upper secondary school, Södra Latin’s drama program near where both boys lived, Varela wanted to do the same.
 The elder Skarsgård gave the young Varela a few hours of acting instructions and he was accepted by the school.
 Varela said he was surprised, because he had shown up in a track suit and looked more like a homeboy/chav than an aspiring actor.
Hrothgar (Old English: "Hrōðgār" ] ; ) was a legendary Danish king living in the early 6th century.

 It served as a palace for King Hroðgar, a legendary Danish king of the sixth century.
 "Heorot" means "Hall of the Hart" (male deer).
 The Geatish hero Beowulf defends the royal hall and its residents from the demonic Grendel.

In the Anglo-Saxon epic Beowulf, Æschere is Hrothgar's most trusted advisor who is killed by Grendel's mother in her attack on Heorot after Grendel's death.
 His name is composed of the Germanic elements Æsc, meaning 'ash', and here, meaning 'army'.
 King Hrothgar describes Æschere as 'min runwita ond min rædbora' (1325), which implies that he knows mysteries or enigmas and also has a duty to explain those mysteries aloud to a community.
 But by killing and decapitating Æschere, Grendel's mother highlights an anxiety within the poem about things that defy human interpretation.
 Beowulf and his Geatish warriors find Æschere's severed head at the entrance to Grendel's mother's lair.
