Bolg appears in the start of the movie to tell his father Azog that he is summoned to Dol Guldur. Later, Azog gives him the mission to slay Thorin and his company of dwarves. Bolg watches as the dwarves are captured by elves of Mirkwood and later launches an attack at the elves when the dwarves makes their escape. During the following battle Bolg wounds the dwarf Kili with a poisonous arrow.

The dwarves manages to escape though but Bolg follows them to Lake-town were his orcs attack the dwarves Bofur, Fili, Oin and Kili who are in the house owned by Bard which means that his children also are in there. As the orcs and dwarves fights the two elves Legolas and Tauriel arrives to the fight. Tauriel stays to help Kili while Legolas fights Bolg. Bolg tries to defeat Legolas by making orcs ambush him during the fight but Legolas defeats them and Bolg escapes on a warg with Legolas pursuing him.
