In the scenes where the Illusive Man smokes, Martin Sheen had to suck on a pen, since he does not actually smoke.
When the character Miranda was first created, she was a blonde of Scandinavian origin named Miranda Solheim. When Australian actress Yvonne Strahovski accepted the role, her surname was changed to the more Australian-sounding Lawson, and her hair color was changed to black to better match her black-and-white uniform.
While Shepard is chasing Vasir in the 'Lair of the Shadow Broker' mission, a wanted poster of Jack appears above a tunnel.
In Miranda's loyalty mission, when she and Shepard get into the elevator, she questions why the elevator cannot move faster. This is a nod to the Citadel elevators in the first Mass Effect; fans used to complain that those elevators were too slow. What is more, when Miranda and Shepard first enter the elevator, the elevator music from the first game is briefly heard.
On the first entry to the Citadel, Captain Bailey mentions that 'spending a year dead' is a common method of tax evasion. This is a reference to Douglas Adams's book 'The Restaurant at the End of the Universe', in which a famous agent spends a year dead for tax purposes.
Throughout the game you encounter three different types of mech: FENRIS (dog-like), LOKI (the most common) and YMIR (large and heavily armed). Each of these names is a reference to Norse mythology: Fenris represents the wolf, Loki the trickster and Ymir the ice giant.
In the game's Overlord DLC, an artificial intelligence announcement is heard at one of the stations: 'To all Cerberus personnel, station-wide music broadcast has been approved to reduce workplace stress.'

Commander Shepard takes his name from American astronaut Alan Shepard; just as Alan Shepard was the first American to go into space, Commander Shepard is the first human Spectre.
In the trilogy, only in this game do you control a character other than Commander Shepard. When the Collectors attack the Normandy and board the ship, you control the pilot Joker for a short section.
At the beginning of the game, when the first Normandy is attacked, Joker's damage report lines 'kinetic barriers down', 'multiple hull breaches' and 'main guns offline' point to the new Normandy upgrades Shepard can buy in the game. Shepard can acquire kinetic barrier, hull armor and main gun upgrades for the new Normandy.
In a shop on Omega you can buy a magazine called Fornax. In the game the magazine only serves to improve your cabin and cannot be read, but in fan art it has often been depicted as a pornographic publication. Game director Casey Hudson has said the name always sounded a little pornographic.
THE WILHELM SCREAM: It is heard when Zaeed blows up the door and the mercenaries are thrown off the walkway by the explosion.
In Mass Effect Legendary Edition it will receive graphics upgraded with the help of artificial intelligence, then touched up by hand. Along with Mass Effect 3, it will be the game that changes the least in the reworked trilogy.
Martin Sheen, the voice of the Illusive Man, says in the Mass Effect 2 documentary DVD that he would not trust this character. He also stated in an interview that he thinks the Illusive Man is a terrible man.
Jack was originally written as pansexual, which would have allowed her to also have a romance with female Shepard. However, Fox News's negative reaction to the first game forced the developers to change this in the final stage of production. In the finished game, although certain scenes between Jack and female Shepard were removed, hints of her sexuality were preserved.
Microsoft released this game as a backward-compatible title on the 2016 N7 anniversary.
A Planet of the Apes reference can be found in the 'Stealing Memory' DLC mission.
Not only is Miranda Lawson's voice provided by Yvonne Strahovski, who played Hannah McKay in the series 'Dexter (2006-2013)', but her face was also designed to closely resemble the actress.

In the 'Stealing Memory' DLC, a Darkspawn Ogre statue from the Dragon Age series, created by the same game developer BioWare, can be found.
