The second season of The Boys will feature an unexpected Lord of the Rings reunion featuring Karl Urban and John Noble, with the latter now cast in the Amazon Prime comic book series as Samuel Butcher, the father of Urban's Billy Butcher.

Karl Urban took to social media to announce Noble's casting in The Boys, sharing a photo of himself alongside his Lord of the Rings co-star. According to Urban, Noble will appear as Butcher's dad in the upcoming seventh episode of the second season of the show, titled Butcher, Baker, Candlestick Maker which is set to be released on Prime Video on October 2nd. "WTF! #lordoftherings @theboystv Mashup," Urban wrote. "John Noble ...aka Denetho Is Butchers dad ep7 Loved working with John His Sam Butcher is a brutal force of nature!"

John Noble played the role of Denethor, the Steward of Gondor, and father to Boromir and Faramir in Peter Jackson's seminal fantasy trilogy. Meanwhile, Urban played Éomer, the leader of the Riders of Rohan. Other than The Lord of the Rings, Noble is most recognized for roles on the small screen in shows such as Elementary, Legends of Tomorrow, and as Dr. Walter Bishop in the science fiction series Fringe.

Coming courtesy of Amazon Prime, The Boys is based on the comic book of the same name by Garth Ennis and Darick Robertson. The series is set in a universe where superpowered individuals are recognized as heroes by the general public and owned by powerful corporation Vought International, which markets and monetizes them. Outside of their heroic personas, most are arrogant and corrupt. The series primarily focuses on two groups: The Seven, Vought International's premier superhero team, and the titular Boys, vigilantes looking to keep the corrupted heroes under control.

Amazon's official description for The Boys season 2 reads; "In a more intense, more desperate Season Two of The Boys, Billy Butcher, Hughie and the team reel from their losses in Season 1. On the run from the law, they struggle to fight back against the Superheroes. As Vought, the company that manages the heroes, cashes in on the panic over the threat of Supervillains, and a new hero, Stormfront, shakes up the company and challenges an already unstable Homelander."

Thanks to the superpowered chaos of the first season, The Boys have been left fugitives and the series begins with their foul-mouthed leader Billy Butcher nowhere to be found. "It's a bit of a mystery," says Urban, on Billy's whereabouts. "The Boys are on the back foot and spend a lot of their time trying to make an impact and get traction for taking down the Supes. Just because they're wanted and in hiding doesn't mean they're gonna stop doing what they do. So, the objective is still fundamentally the same."

Several episodes of the second season have now been released on Amazon Prime, with episode releases being staggered weekly before culminating in an epic season finale on October 9. The Boys has already been renewed for a third season. This comes us courtesy of Karl Urban's official Instagram account.
