- Actor Allusion:
- Marvin comments to Victoria that he remembers the Secret Service being tougher. John Malkovich, who played Marvin, also played the would-be presidential assassin Mitch Leary in the movie In the Line of Fire.
- Frank declares a lock to be Unbreakable.
- Mary-Louise Parker's character briefly gets high.
- Victoria is played by Helen Mirren, and was the name of a Queen of England.
- In Red 2 she pretends to be crazy, claiming she is the Queen of England.
- Bruce Willis' character makes a false report of "officer down" on a police radio to turn things to his advantage during a car chase, like he did in Die Hard with a Vengeance.
- Anthony Hopkins is introduced listening to classical music, and is later in the movie locked in a cage. From which he escapes calmly, but violently.
- All-Star Cast: One of the best and most impressive of that year, only surpassed by that of The Expendables and Inception.
- Awesome, Dear Boy: Helen Mirren loved working on Red so much, thanks to the action-heavy role she had in the film, that she has said "I'm there!" to any planned sequel. There was a sequel, and Helen was delighted to be in it.
- Warren Ellis agrees, saying that despite having minimal input on the very loosely-adapted film, getting to write something that led to Helen Mirren wielding an M60 is a career highlight.
- Casting Gag: Vice President Stanton's actor Julian McMahon is no stranger to politics, being the son of former Australian Prime Minister William McMahon.
- Fake Russian:
- Brian Cox (a Scot) as Ivan in both movies.
- Even less convincing with Catherine Zeta-Jones (Welsh) as Katya. True Russians never waste good alcohol.
- In Name Only: Although Warren Ellis admits they couldn't have directly adapted the comic into anything more than an hour.
