The actress also chats about being a part of the massive films.
Long before Evangeline Lilly became a part of the sprawling Marvel Cinematic Universe, she was used to grappling with roles in incredibly mysterious projects.
ET's Kevin Frazier caught up with the stunning 39-year-old actress on the purple carpet for Avengers: Endgame on Monday night, where she discussed playing the fugitive Kate Austen on Lost and how it inadvertently helped her when taking on playing the Wasp.
"Is it weird? No, because I started my training as an actor on a show called Lost, where I was always doing something that I had no idea about and everybody wanted the answers for, so I am well-seasoned in this world," she explained in a flowing red pantsuit.
While on hand, Lilly also discussed the communal impact of the hit show, which went off the air in 2010.
"For me, what made Lost so special was that we reached an era where mom, dad and kids all had a TV in their own room or a laptop on their lap and everybody was watching television separately," she said. "Which, originally when TV first came out, it was marketed as an activity the whole family could enjoy and it kind of brought people together around the fire so to speak, the proverbial fire. And that had changed and it had become an isolating tool, and I loved that our show really brought everyone together around the TV again. Mom, dad, kids, grandmas, grandpas, uncles, co-stars, there were parties... and I loved that about our show."
In Ant-Man and Ant-Man and the Wasp, Lilly plays Scott Lang's (Paul Rudd) love interest and sidekick Hope van Dyne as they battle villains of all sizes. Although it's not clear how big a role she'll have in Endgame, promotional materials have shown plenty of Rudd. And theories abound that he could play a huge role in the super squad's scheme to bring back their fallen friends.
Although she didn't discuss the film, Lilly did share her response to being a part the massive project.
"It's like being a part of the biggest most pumped-up rock show of all time, and I get to be here and I get to be one of the rock stars and that's cool as s**t!" she shared.
Avengers: Endgame arrives in theaters on Friday.
