- Awesome Music:
- This orchestral piece in the teaser trailer: Xap's "The Hit House". It works well with the Mickey Mousing in action sequences, whether it's a line of soldiers being gunned down by rifle fire, sword fights or the final chanting montage at the end.
- "War Pigs" by Black Sabbath which was used in the official trailer. The lyrics from the first stanza perfectly fit the scenes shown in the trailer, and it keeps the trend of using awesome rock songs in the Kingsman franchise going.
- Hilarious in Hindsight:
- Ralph Fiennes has quite a history of playing a neatly dressed British secret agent. First there was John Steed, then there was Gareth Mallory / M, and now he's one of the founders of Kingsman. This time he even combines the Sword Cane umbrella, Edwardian fashion suit and bowler hat (like Steed), and being officer of a secret service (like M).
- Djimon Hounsou, after being involved in the formation of the Round Table in King Arthur: Legend of the Sword, is involved in yet another formation of the Round Table, albeit this time an organization that takes cues from the Arthurian Knights.
- Stanley Tucci plays Merlin. Again.
- Tucci and Mark Strong look very much alike as often noted. Now both have played Merlin in the Kingsman series.
YMMV / The King's Man
