* HeyItsThatGuy:
** Nana Visitor AKA Major Kira Nerys from Deep Space Nine as Madame X/Dr. Elizabeth Renfro
** John Savage as Lydecker counts for anyone who's seen ''Film/TheDeerHunter''.
** Hey! [[Series/{{NCIS}} Tony DiNozzo]] is Logan! And Michael Weatherly has said he was inspired by ''Dark Angel'''s Alec.
** ''Series/{{Battlestar Galactica|Reimagined}}'': Sharon/Boomer (Grace Park) as a female breeding X5, Leoben (Callum Keith Rennie) as a sheriff, Chief Tyrol (Aaron Douglas) as a hotel manager, Tory (Rekha Sharma) as Dr. Beverly Shankar, Crashdown (SamWitwer) as a transgenic named Marrow, Cally (Nicki Clyne) as an X6 named Fixit, Dualla (Kandyse [=McClure=]) as Joshua's girlfriend Annie Fisher, Narcho (Sebastian Spence) as Tinga's husband Charlie Smith, Elosha (Lorena Gale) as a teacher, Simon (Rick Worthy) as Detective Ramon Clemente, Gaeta (Alessandro Juliani) as Max's work friend Druid.
*** Grace Park is the only actor to have played both a transgenic and a Cylon.
** ''Series/{{Caprica}}'': Agent Durham (Brian Markinson) as Dr. Sam Carr.
** ''Series/{{The Office|US}}'': Dwight Schrute (Rainn Wilson) as Phil, the "superhero" who gave Logan his exoskeleton.
** ''Series/{{Supernatural}}'': Mary Winchester (Samantha Smith) as Logan's ex-fiancée Daphne. Meg Masters (Nicki Aycox) as Max's sister Syl.
*** This is funny, as it means JensenAckles and Nicki Aycox, in addition to playing enemies on ''Series/{{Supernatural}}'', have played brother and sister on ''DarkAngel'', although Ben and Syl didn't appear onscreen together.
*** If we're going down that route, then this also means that Max's love interest was engaged to the woman who becomes the mother of her ''sort of'' ''[[{{VitriolicBestBuds}} partner-in-crime]]''. And considering it's a bit of a running gag in the fandom (especially of Alex/Max shippers) that Logan was a lot older than then 19y/o Max, having Mama!Winchester his ex-fiancée just about proved the point.
