The highly anticipated second season of Prime Video’s Fallout just added another big name to the cast.

According to a Deadline report on Thursday, Macaulay Culkin has a recurring role in Season 2 of the video game adaptation. Details are a bit scarce, but according to the article, he is said to be playing a crazy genius character. IGN has reached out to Prime Video for more details.

Culkin joins a cast that also includes Ella Purnell, Aaron Moten, Kyle MacLachlan, Moisés Arias, Xelia Mendes-Jones and Walton Goggins. As the report notes, Culkin, who of course broke out as a child star in Home Alone, has already worked with Prime Video, where he voiced a character in the animated series The Second Best Hospital in the Galaxy.

Culkin’s reported casting is one of the few details we’ve gotten about Season 2, which was ordered quickly after Fallout became a big hit for Prime Video. According to Amazon’s own figures, the series attracted a whopping 65 million viewers in its first sixteen days, making it the second most-watched show on Prime Video. It also reignited interest in the games series, with Microsoft CEO Satya Nadella saying earlier this year that it drove a nearly fivefold jump in hours played for the franchise on Game Pass.

As for when we can expect to see Culkin and his crazy, genius character in season 2, we’re not quite sure yet. Showrunners Geneva Robertson-Dworet and Graham Wagner previously assured fans that they are “moving as fast as we possibly can” when it comes to releasing season 2, so hopefully it won’t take too long.

In the meantime, you can read IGN’s 9/10 review of season 1, where Matt Purslow wrote, “A bright and funny apocalypse full of dark punchlines and bursts of ultra-violence, Fallout is among the best video game adaptations ever made.”
