Mr. House (Robert Edwin House) is the pre-war billionaire tech genius who saved Las Vegas from nuclear destruction and now rules New Vegas from the shadows. In Fallout Season 2, he's played by Justin Theroux, appearing in flashbacks and as a major player in the present-day conspiracy involving Hank MacLean.
House is one of the most iconic characters from Fallout: New Vegas (2010), and his live-action debut has been highly anticipated by fans.
Robert House: The Man Who Saved Vegas
- Created the Pip-Boy (worn by Vault dwellers)
- Built the Securitron robot army
- Designed a missile defense system to protect Las Vegas
- Predicted the exact date of the nuclear war
How He Survived: House put himself in a life-support chamber before the bombs fell. His missile defense shot down 77 of 78 warheads targeting Vegas. The city—and House—survived.
200 Years Later: House has ruled New Vegas for over two centuries, kept alive by technology, waiting for the right moment to rebuild civilization on his terms.
The Two Mr. Houses Twist
Season 1's Mr. House: In the Season 1 finale, we briefly saw a mustachioed man at the Vault-Tec meeting, played by Rafi Silver. Fans assumed this was House.
Season 2's Revelation: Justin Theroux plays the *real* Robert House. The man from Season 1? A body double—House's public-facing decoy to protect his true identity.
Why Two Actors?: Amazon didn't recast the role. Both versions of House exist in the story. The paranoid billionaire used a stand-in for public appearances while the real House operated from the shadows.
Theroux's Portrayal: The Season 2 premiere shows House as cold, calculating, and willing to use horrific technology on innocent people to test his inventions.
House and the Mind Control Chip
The Opening Scene: Season 2 Episode 1 opens with House in a pre-war bar, testing a brain-computer interface chip on an unwilling construction worker. He forces the man to attack his friends, then causes his head to explode when the device overloads.
RobCo's Dark Side: While House publicly built helpful technology like Pip-Boys, he was also developing mind control devices. This technology was tested in Vault 24.
Connection to Hank: Hank MacLean traveled to a Vault-Tec facility at episode's end to contact House directly. They're working together on the mind control technology—and Hank wants to "miniaturize" the chip for new purposes.
Mr. House in the Games
- Work for House to drive out the NCR and Legion
- Betray House and kill him
- Help House achieve his vision of an independent Vegas
His Philosophy: House believes democracy failed humanity. He wants to rebuild civilization under his autocratic control, using technology and capitalism to achieve what governments couldn't.
The Lucky 38: House's base of operations is the Lucky 38 casino, where he remains in his life-support chamber, communicating through screens and Securitrons.
His Plan: In the games, House wanted the Platinum Chip to upgrade his robot army. In the show, he's focused on mind control technology—a darker path to the same goal of total control.
