Justin Theroux returns as mysterious Mr. House in Fallout season 2—what to expect from his complex role

Justin Theroux is set to reprise his role as Robert Edwin House in Fallout season 2, continuing the story of the enigmatic figure known as Mr. House. As the new season approaches later this year, fans are keen to learn more about this character’s intricate background and how he will fit into the series’ unfolding narrative.

Understanding the character of Robert Edwin House in the upcoming season

In Fallout season 2, Theroux portrays Robert Edwin House, the former CEO of RobCo Industries and the powerful owner of the Lucky 38 casino, as well as the ruler of the New Vegas Strip. This complex character was first introduced in Fallout: New Vegas, the 2010 video game, where he is commonly called Mr. House. Although the first season of the show briefly featured the character, he was portrayed by Rafi Silver at that time.

Before the nuclear devastation, House anticipated the arrival of global war and invested heavily in building a personal army of securitron robots along with advanced anti-missile defense systems. These defenses were intended to protect Las Vegas from the widespread destruction seen in cities like Los Angeles and Washington D.C. While House’s efforts spared Las Vegas from total ruin, the city still suffered damage during the war.

Central to House’s long-term plans was the Platinum Chip, a critical software upgrade for his robot army. However, the chip was lost on the day the bombs fell, presumed destroyed in the nuclear fallout. This setback prevented House from consolidating control as he had envisioned, forcing him to cryogenically freeze himself. Due to a software error, he remained in stasis for nearly two centuries before awakening to a changed world.

Mr. House’s role in reshaping Las Vegas after the war

Upon waking, House found Las Vegas in ruins and occupied by various tribes. Over time, he managed to unite these disparate groups into the Three Families, creating the foundation for the city now known as New Vegas. To regain his power, Mr. House dispatched his securitrons to recover the Platinum Chip. Eventually, the chip was located and was to be delivered by The Courier, the main character of Fallout: New Vegas.

However, Benny, the leader of one of the Three Families, ambushed The Courier, stole the Platinum Chip, and left The Courier for dead. In the video game, the player‘s choices determine Mr. House’s fate—ranging from his grand vision for New Vegas becoming reality to being overthrown or simply eliminated by The Courier, who may side with other factions in the Mojave Wasteland.

Challenges in adapting the narrative for the TV adaptation

Since Fallout’s video games offer multiple endings and branching storylines, defining what is canonical for the television series is complex. The RadioTimes.com Gaming Team has noted this difficulty in predicting how the show will handle Mr. House’s story moving forward. Jonathan Nolan, the show’s director, has mentioned that the series was not created to satisfy all fans of the games, suggesting that some viewers may have differing opinions once season two is released.

The uncertainty surrounding Mr. House’s canonical fate post-Fallout: New Vegas means the show may focus on his actions leading up to the war or create new developments that diverge from the games’ plots. This open-ended approach leaves room for creative exploration of the character’s motivations and influence within the Fallout universe.

The impact of Theroux’s portrayal on Fallout season 2

Justin Theroux’s return as Mr. House adds depth given his nuanced performance of a character balancing vision and control amid chaos. As the story advances, his role could reveal more about the power dynamics in the post-apocalyptic setting of New Vegas and the ongoing struggles between its factions.

With Fallout season 1 available to stream on Amazon Prime Video, viewers are positioned to catch up before the new episodes arrive. The continuation promises to expand the storyline of one of the franchise’s most enigmatic figures, potentially reshaping familiar narratives from the video game to fit a serialized TV format.
