Mother and son unite! Jamie Lee Curtis took her son, Thomas Guest, to the premiere of the film Warcraft in Los Angeles on Monday, June 6, and the duo went all out, cosplaying in green makeup and head-to-toe costumes.

The film, which is based on the popular video game series of the same title, is set in the world of Azeroth, where humans and Orcs coexist.

The actress, who has an appreciation for video games, wore a headpiece, red cloak and carried with her a scepter. Her 20-year-old son was equally decked out in black and gold, and held a giant mallet. 

“We’re serious about our games,” Curtis told Entertainment Tonight at the event.

So serious that she even joined fans in screaming “Leeroy Jenkins” in a video posted to her Twitter. “Leeroy Jenkins” is the popular internet meme that emerged in 2005 after a player named Ben Schulz created a video in which an ill-informed player runs into the battlefield alone while yelling the name, causing everyone on his team to die.

This isn’t the first time that Curtis has gotten into character. She also cosplayed at BlizzCon 2015 and competed with her son at Evo 2015.

Warcraft — which stars Paula Patton, Travis Fimmel, Ben Foster and Dominic Cooper — hits theaters June 10.
