Robin Simone Givens (Tyson/Marinkovic)

Regrettably, best known to the general public as Mike Tyson's abused wife, Robin's a talented actress who started out doing comedies like The Cosby Show and her starring role in Head of the Class, then moved on to drama, sci-fi, crime / law, and even hosting a reality tv series, Forgive or Forget.
She also did a stint on Broadway, singing and dancing as Roxie Hart in Chicago.
Robin recently did semi-regular turns on both Tyler Perry's House of Payne and (as herself) on the dramedy The Game.

Genre appearances include...
Chuck (Jane Bently)
Nikita "All the Way"
Enemies Among Us (Gloria)
Little Hercules in 3-D(Dana)
AntiBody(Dr. Rachel Saverini)

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?)
