Dichen Lachman has confirmed that she will be appearing as DC Comics villain Roulette in Season 2 of “Supergirl.”

In a video clip she shared on Instagram, Lachman thanked her fans for all the excitement surrounding her casting and talked a little bit about her experience in filming the CW series.

“I just want to thank everybody for all the excitement about me appearing on ‘Supergirl’ as Roulette,” the 34-year-old Nepali-born Australian actress said. “The cast and crew are working so hard and there are such incredible people. I’m really excited to be on the show, and I can’t wait for you to see it.”

On Twitter, Lachman revealed why joining the cast of “Supergirl” was pretty surreal for her.

“When I was a little girl in Kathmandu I used to daydream about being Supergirl,” she tweeted. “[It’s] one of the few movies we had on VHS. Watched it many times.”

In a follow-up tweet, Lachman added: “‘Supergirl,’ ‘Superman’ and ‘Police Academy’ were the 3 tapes we had and we watched them over and over again when we had electricity.”

In the comics, Roulette, also known as Veronica Sinclair, is an enemy to the Justice Society. She runs a gambling establishment for supervillains where they can bet on different events like captive superhero death-matches. Rather than getting her own hands dirty, she is more of a calculating business-minded character who manipulates others for profit. Created by Geoff Johns and Rags Morales, Roulette first appeared in 2001’s “JSA Secret Files and Origins” #2.

On CW’s “Supergirl,” on the other hand, Roulette runs an underground alien fight club in National City and is eager to get the Girl of Steel in the ring, Comicbook.com reported.

According to TVLine, Lachman — whose recent TV acting credits include “The Last Ship,” “Agents of S.H.I.E.L.D. “ and “The 100,” among many others — will appear in "Supergirl" Season 2, Episode 4.
