- Peter DeLuise, who wrote 'Enemy Mine', named Lorne after his brother-in-law, Lorne Loader.
- Because of the nature of his mission with SG-11, Lorne is sometimes assumed by fandom to have a geological engineering background.
- Originally, Kavan Smith was to have played a different character entirely on Stargate Atlantis. Kavan Smith has stated that he eventually reprised the role of Lorne due to positive fan reaction.
- Initially slated to appear in one episode of Stargate Atlantis only, Lorne became a recurring character entirely due to his popularity with fans.
- Lorne is never officially named as Colonel Sheppard's second in command, though various episodes seem to imply that he is. Stargate Atlantis: The Official Companion, Season 2 by Sharon Gosling states that Lorne acts as Sheppard's "right-hand man".
- It also incorrectly states that Kavan Smith's character in Stargate SG-1 was named Major Lawrence. This suggests that the character Smith was to have originally played on Stargate Atlantis may have been called Lawrence.
- The make-up of Lorne's gate team on Atlantis is uncertain, though it is primarily shown as being comprised of Lorne and three marines.
- Lorne was believed to have been killed once during his run on Stargate Atlantis and was visibly injured only once. It was also mentioned that his character was infected by a Wraith pathogen off-screen.
- Lorne was one of Carson Beckett's pall bearers after his death. This followed Lorne turning down an invitation to go fishing with Beckett in favour of painting a view of Atlantis.
- The painting from this episode would later make an appearance in episode 4.20 of Stargate Atlantis, 'The Last Man', hanging on a wall in General E. Lorne's office at the SGC.
- Lorne's first name was revealed in episode 3x20 of Stargate Atlantis, 'First Strike'. Although never actually spoken aloud, it appeared on his flight suit aboard the Daedalus and whilst piloting an F-302.
- A scene was planned for episode 4x12, 'Spoils of War', where a character would call him Uncle Evan, but this scene was cut for time.
- Before he was given an official first name, fans referred to Lorne as either Nick or Marcus.
- In addition, issue 46 of Stargate SG-1: The DVD Collection gave his first name as Stephen. This was corrected for issue 75 of Stargate Atlantis: The DVD Collection.
- In 2009, Lorne was the central character in the Stargate Atlantis audiobook, Impressions.
- The 2010 novel Death Game by Jo Graham gives us more information about Lorne's background:
I was conceived in the summer of '69, the Summer of Love, right? My dad had been drafted so he and my mom went on a road trip, one last blast before She'd just gotten back to San Francisco and he'd reported in when she out she was pregnant. Strange time, you know? She moved into this apartment in Haight Ashbury with this guy she'd met on the trip, my Uncle Ron. It wasn't like that. Uncle Ron is gay so they were just roommates. You know, with my dad gone and all. He got sent overseas. He was in the middle of his tour when I was born, on April 30. May Eve, my mom used to say, like that made me special.
My dad's an okay guy. It just didn't work out between them. When he got home he was too different and it was all too different. He wasn't so much into the scene, and he couldn't stand the city. He wanted somewhere big and quiet, where he could hear himself think, somewhere totally unlike the jungles of Southeast Asia. He works for the Park Services in Arizona now. Big sky and mesas, Navajo country. He was married to a woman who was half Navajo for a while, but they broke up. My sister Dorinda's a quarter Navajo, though. She's a great kid. She's married and has a baby, and she's in veterinary school in Phoenix now. She's got it all together.
My dad believes in UFOs. He thinks that there are really spaceships and that aliens have visited Earth before. People think he's kind of crazy that way. I wish I could tell him, sometimes, that he's not. That I've walked around on other planets and seen the damndest things. That there really are spaceships, and that you've never lived until you've taken the Tok'ra to a bar in Colorado Spints. Maybe one day I will. I think my dad can keep his mouth shut a lot more than he lets on.
But I didn't grow up with him. I grew up in San Francisco with my mom. She's an art teacher. She does all kinds of fabric art, painting on silk and weaving with raw fabrics, but you can't make a living doing that. So she teaches art to little kids at school. She says she really enjoys it because their minds are fresh. They haven't learned what they can't do.
I could have gone to college without the Air Force. My dad said he'd help, and Uncle Ron and Uncle Gene did too, and by then my mom was married to Boris, so it wasn't like it was just her who'd have to come up with the money. But it was what I really wanted.
No, my mom wasn't thrilled, but she wasn't mad either. See, my mom? She's the world's biggest optimist. She believes in a Star Trek future. We're going to reach this place where we don't have wars anymore, and everyone is judged on their merits, not by the colour of their skin or their gender or their sexual orientation. She thinks we can get there in two or three hundred years if we really try. She says look where we've come in the last three hundred years. Nothing is impossible.
And I'm with her. I believe in that Star Trek future too. I just think you can't get there without Starfleet, without the people who go out and keep it safe, the people who explore and who make it real. They're both so sure, my mom and dad, in their own ways. They're both so sure that it could all be true. So I guess it wasn't much of a shock to me to find out it was. The first time I walked into that gateroom in Cheyenne Mountain, it was like coming home. Yeah. This is the thing. This is the real thing, the thing I'm doing. Cause anything can be true if you make it so.
