Actor Elizabeth Tulloch is set to play Lois Lane in this December’s three-show crossover between CW's Supergirl, The Flash and Arrow. Following the announcement, Tulloch expressed her excitement to be taking on the role and praised former Lois Lane portrayer Margot Kidder.

Tulloch posted on Instagram, writing, "I am so excited... to be playing the iconic Lois Lane on the Arrowverse crossover episodes... When I started acting, one of my teachers asked me to watch the screen tests for the role of Lois Lane for 1978’s Superman. All of the actresses were terrific, but it was always clear to me why Margot Kidder won the role: she seemed lit from within, full of joie de vivre. Now, at a time when the noble profession of journalism feels under siege, it’s a privilege to join the club of actresses who have played the dogged reporter."

The actor also praised Lois Lane as a character, writing, "As far back as 1938 when she first appeared in Action Comics #1, Lois Lane has defied and subverted society’s expectations of how women should behave. She was portrayed as opinionated, inquisitive, and an unapologetically badass career woman at a time when many representations of women leaned more towards meek and demure."

"One of the reasons the character has remained so compelling for the last 80 years," she continued, "is that she has all these formidable, strong-willed qualities, but she’s also vulnerable, romantic, and feminine. A truly modern woman."

Tulloch will make her debut alongside Kate “Batwoman” Kane, as played by CW newcomer Ruby Rose. Rose was cast in the role last month.
