Joined by her son, Thomas Guest, the two Warcraft superfans rocked green face paint and some stunningly intricate costumes to the TCL Chinese Theatre in Hollywood for the premiere of the long-awaited sci-fi/fantasy epic, based on the wildly-popular multi-player online video game, World of Warcraft.
Curtis and Guest stopped to talk with ET's Ashley Crossan about their wild outfits, and the 57-year-old Golden Globe winner explained, "We're serious about our games."
Curtis also opened up about being introduced to Blizzard Entertainment's addictive MMORPG by her son.
"My son Tom is a player and I'm a supporter," Curtis shared, before adding that she loves the expansive digital fantasy realms in Warcraft as well. "I think that what Blizzard has done has changed the universe."
And for Curtis, Blizzard's exciting game has certainly changed things in her own life, including building a stronger relationship with her teenage child.
"The astonishing thing about being a parent is that your children bring things to you that you would never, ever, ever, ever know," Curtis explained. "And you hope that you bring a few things to them that are interesting."
Curtis and Guest aren't the only parent/child duo brought together by Warcraft. Director Duncan Jones recently spoke with ET about his how father, late music legend David Bowie, had seen a rough cut of the film before his death in January and was proud of Jones for what he'd accomplished as a filmmaker.
"He was just excited for me to be branching out and trying out different things," Jones recounted. Check out the video below to hear more from the acclaimed director. Warcraft explodes into theaters on Friday.
