 Beorn arrives to the Battle of the Five Armies atop a Great Eagle rather than on foot and does not slay Bolg, who is killed by Legolas in the film adaptation (the Orc commander was also changed to be Azog himself, but Thorin, instead of Beorn, kills Azog in single combat).In the DVD commentary, the production team explained that they normally take great care that characters only speak with accents which were historically present in the British Isles, but they made a major exception for Beorn by letting Persbrandt use his natural Swedish accent.They reasoned that Beorn should logically have a very distinctive and foreign-sounding accent, given that he is the last survivor of an isolated race which had little contact with people from regions such as Gondor or the Shire.
