Arrowverse Role: Supergirl as Eliza Danvers
Other DC Universe Roles: Supergirl (1984) as Kara Zor-El/Linda Lee/Supergirl, Batman: The Animated Series as Talia al Ghul, Smallville as Lara-El, DC Super Hero Girls as Martha Kent
It’s hard to deny that 1984’s Supergirl movie isn’t anything special – in fact, it’s actually pretty terrible – but leading lady Helen Slater gave it her best shot and delivered a pretty charming performance as the Girl of Steel. Even if the movie was a flop, the actress must have struck a chord with fans, as she’s featured in several DC productions since.
In a couple of these, she swapped being Superman’s cousin for his mother – she played Kal-El’s biological mother, Lara, in Smallville and then his adoptive one, Martha Kent, in DC Super Hero Girls. Though it wasn’t Superman-related, she also turned up as femme fatale Talia al Ghul on Batman: The Animated Series.
Currently, she’s starring in Supergirl as Eliza Danvers, adoptive mother of Supergirl. Her on-screen husband is also no stranger to the DC universe…
