* HeyItsThatGuy: [[Series/OnceUponATime Emma Swan]], [[{{Scandal}} Olivia Pope]] and [[Series/LawAndOrderSpecialVictimsUnit Alex Cabot]] (Ow Owwwwww) are Jane's fellow assassins.
* HeyItsThatVoice: We only see a reflection of his face, but anyone who's played all the ''Franchise/MassEffect'' games will recognize [[KeithDavid Admiral Anderson]], or ''{{Gargoyles}}'''s Goliath if you prefer, running Jane's assassin firm.
** Not to mention, Angela Bassett running John's assassin firm.
* RealLifeRelative: Not at this stage but soon afterwards. Already well publicized before the movie came out, to the point that some initially assumed that this was a Gigli-style attempt at capitalizing on their romance. Apparently, they fell in love on the set.
* RomanceOnTheSet: Pitt infamously left Jennifer Aniston for Jolie while filming.
* ThrowItIn: The scene where John accidentally shoots through Jane's windshield was supposed to have him hopping over the last fence, but Brad Pitt actually tripped and broke the fence. However, his muttered line of "Oh, dear God!" as he rushed through the mangled fence was so amusing that the director kept the scene the way it was.
* WhatCouldHaveBeen: Brad and Angelina were both replacements when filming began to snarl. Before the two of them were confirmed, others such as Creator/WillSmith, Creator/JohnnyDepp, Creator/NicoleKidman, and Catherine Zeta-Jones were considered. Now try to imagine both A) the movie with any combination of the previous actors, and B) a world without Brangelina.
