Arrowverse Actors Who Have Appeared in Previous DC Shows and Movies

LAST UPDATED: January 14, 2020 (prior to the airing of Crisis parts 4 and 5)

This is an attempt to catalogue the various Arrowverse actors who have appeared in previous DC productions. Note that while I’ve tried to keep spoilers to a minimum, in some cases they are avoidable so if you aren’t caught up, read at your own risk. This list will be updated as more actors appear, new seasons air, and overlooked appearances are discovered. Please do let me know what I’m missing. At this point I’m limiting things to DC actors, the reason being that actors having appeared previously in a Marvel production doesn’t seem to increase their chances of landing an Arrowverse role. Should that change, I’ll add the Marvel actors in later.

I use Show Name, Show Start Year regardless of whether the actor appeared in that particular year, Character Name/s, Season(s) only for live action shows lasting more than one season, and Whether Cast, Guest (latter two TV), Movie, or Animated Short. For purposes of this list, actors who appear in every or nearly episode of a season are considered Cast regardless of their official classification.  To avoid any preferential treatment, actors are listed in order of last name. All prior live action DC work noted; for animated work only the best known work noted as voice actors tend to appear in many productions.

For purposes of this list, the Arrowverse is defined as the four live action superhero shows on the CW in 2016-2018+: Arrow (2012), Flash (2014), Supergirl (2015), and DC’s Legends of Tomorrow (2016). The reason the list counts Supergirl but not Flash (1990) when both have been shown on Flash (2014) to be on parallel Earths is simply because Supergirl is part of the current wave of shows while Flash (1990) is a long ended show.  Gotham (2014), while a contemporary of the Arrowverse shows, is on FOX and not connected to the Arrowverse. Actors whose sole DC work occurred subsequent to Arrow’s premiere in 2012 are not currently being tracked.

Arrowverse Work: Flash (2014): Wade Eiling (Guest Season 1)

Note: Eiling is a corrupt soldier who in the comics is an enemy/sometimes uneasy ally of Captain Atom. While Brown has voiced a number of roles, Superman’s arch nemesis Luthor is by far what he’s most known for DC-wise.

Dean Cain

Older Work: Lois & Clark: The New Adventures of Superman (1993): Superman/Clark Kent (Cast); Smallville (2001): Curtis Knox (Guest Season 7)

Arrowverse Work: Supergirl (2015): Jeremiah Danvers (Guest Season 1-2)

Note: Cain plays Supergirl’s adoptive father on Supergirl; both this role and his appearance as a villain on Smallville were undoubtedly due to him playing Superman on Lois & Clark.

Lynda Carter

Older Work: Wonder Woman (1975): Wonder Woman/Princess Diana/Diana Prince (Cast); Smallville (2001): Moira Sullivan (Guest Season 6)

Arrowverse Work: Supergirl (2015): President Olivia Marsdin (Guest Seasons 2 & 4)

Arrowverse: Supergirl (2015): Lex Luthor (Guest Seasons 4-5); Batwoman (2019): same (Guest Season 1); The Flash: same (Guest Season 6)

Vito D'Ambrosio

Older Work: Flash (1990): Bellows (Cast)

Arrowverse Work: Flash (2014): Mayor Anthony Bellows (Guest Seasons 1-4)

Alex Désert

Older Work: Flash (1990): Julio Mendez (Cast)

Arrowverse Work: Flash (2014): Julio Mendez (Guest Season 3)

Note: J”onn’s Noel Neill alias is a tribute to the actress of the same name who, like Durance, played Lois Lane (Neill played her on The Adventures of Superman). Durance replaces Laura Benanti as Supergirl’s mother Allura on Supergirl. During the Crisis on Infinite Earths crossover she played both Allura and the Lois Lane from Smallville.

Arrowverse Work: Arrow (2012): TV Anchorman aka TV Field Reporter aka News Reporter aka Merrit Davis (Guest Seasons 1-2, 4-5, 7)

Note: Green frequently plays reporters in TV movies and series. It’s unclear if all his appearances as a reporter on Arrow are the Davis character or if they are different reporters.

Arrowverse Work: Flash (2014): The Trickster/James Jesse (Guest Season 1-2), The Trickster/James Jesse of Earth-3 (Guest Season 3)

Note: Despite his many years voicing the Joker, it was most likely his Trickster role that got him into Flash (2014). All versions of the Trickster are Flash enemies. In the current Flash series his Trickster is the father of a younger Trickster.

Teri Hatcher

Arrowverse Work: Supergirl (2015): Minister (Guest Season 3)

Notes: Green Guardsman is an homage to the 1940s Green Lantern (Alan Scott). His guest appearance on Supergirl as a minister, however, probably owes less to his previous animated DC work than it does to playing Ralph Hinkley on The Greatest American Hero.
