- Fili and Kili are in this scene, but Kili was injured by Orcs in another battle, and Fili, along with Bofur and Oin stayed behind to watch him, so Fili and Kili should not be in this set.
- This set is the first since The Hobbit: An Unexpected Journey to contain Dwarves in Thorin's Company other than Thorin Oakenshield himself, as he appears in all 3 subthemes.
- This is the only set in any The Hobbit or The Lord of the Rings set not to include any exclusive minifigures (except for Smaug, but he is a brick-built character), excluding 9469 Gandalf Arrives and 79001 Fleeing from the Spiders of Mirkwood, though all three include exclusive variations
- It is the largest set in The Hobbit, but 9474 The Battle of Helm's Deep and 10237 The Tower of Orthanc (both in The Two Towers, subtheme of The Lord of the Rings) are larger
