Helen Rachel Schlacter

It's not often an actress can play a character, then play the character's aunt 24 years later. and finally, the character's adoptive mother 7 years after that!
Helen was the first actress to play Supergirl / Kara Zor-El in any medium in Supergirl: the Movie (1984)!
In 2008, she played Kara's aunt, Lara-El (mother of Kal-El / Clark Kent / Superman), in two episodes of Smallville! (She also appears in a documentary on the Season 7 Smallville DVD set entitled "Supergirl: Last Daughter of Krypton")
And, most recently, in 2015, she was Eliza Danvers, adoptive mother of Linda Danvers / Kara Zor-El / Supergirl)
And she still looks...well...SUPER!

From her first featured role in The Big Doll House, Pam Grier was THE female action star of the 1970s, dominating the blaxplotation genre along with appearances in several horror flix.
Honing her acting skills, she moved to drama and comedy film & tv work, including multi-episode arcs on Crime Story and Miami Vice and as a regular on Linc's.

Kristin Laura Kreuk

Kirsten has a good acting range, and handled the action sequences in the Street Fighter: the Legend of Chun-Li adquately.
I didn't expect Michelle Yeoh-level stuntwork.
Kirsten looked convincing in the medium shots and closeups.
At least she wasn't worse than Ming-Na in the 1994 flick! (Cute, but terrible fighting skills!)

Currently, she's starring on the CW in the remake of the 1990s series Beauty and the Beast.
While I'm hoping it'll last, making the so-called "beast" a handsome guy with a scar and a temper instead of a creature who Catherine helps tame his beastly tendencies with her love indicates a serious lack of faith in the audience to accept a physically-unattractive, but intelligent and emotionally-open, man as a romantic lead the way fans of the original series did.

Trivia: Kristen as Lana Lang, played opposite Annette O'Toole (who had played Lana in Superman III) as Martha Kent in Smallville, marking one of the few times two people who played the same non-costumed character appeared together onscreen. (Yes, there have been episodes of series where, for example, Adam West or Buster Crabbe appeared opposite newer versions of Batman or Buck Rogers, but how often did actors playing the two generations of supporting characters appear together?)
