'Home Alone' star Macaulay Culkin proves a brutal force in 'Fallout' season 2

Macaulay Culkin has traded his Home Alone antics for a dark turn in Fallout season 2, making a shocking debut as Lacerta Legate in episode three, which aired Wednesday, Dec. 31. 

The 45-year-old star steps into Caesar’s Legion, proving he’s just as fearless in the wasteland as he was in the family-friendly classics of his youth.

Culkin’s character faces off with Lucy (Ella Purnell), who is captured and mounted on a cross in the Legion camp. 

Despite desperate pleas and offers to broker a truce, Lacerta remains cold and unyielding until Walton Goggins’ Ghoul swoops in to save her, leaving the camp in fiery chaos.

Goggins, who previously worked with the Richie Rich star on HBO’s The Righteous Gemstones, admitted he had no idea his former co-star was joining the series. 

“I just lit up because I think the world of him,” he told PEOPLE, adding that Culkin’s role “goes to places you won’t even expect.”

Showrunner Geneva Robertson-Dworet raved about Zootopia 2 actor’s performance, praising his “very particular read” on the character and calling the idea of the innocent Home Alone boy now running a brutal slave society “deliciously fun.”

As the season heats up, Fallout is set to plunge deeper into a war between Caesar’s Legion, the New California Republic, and the Brotherhood of Steel. 

For those unfamiliar, new episodes drop every Wednesday on Prime Video, leading to a finale on Feb. 4, 2026.
