Fallout: New Vegas Voice Cast & Character Guide

Why the voice cast stands out

New Vegas uses recognizable performers without turning the cast into a celebrity showcase. The strongest performances are tightly matched to the writing: House sounds controlled and aristocratic, Caesar sounds certain of his own doctrine, and companions such as Boone or Veronica are given enough restraint to feel like residents of the Mojave rather than exposition machines.

Major character voices

René Auberjonois voices Mr. House, Matthew Perry voices Benny, John Doman voices Caesar, Dave Foley voices Yes Man, Felicia Day voices Veronica Santangelo, Zachary Levi voices Arcade Gannon, Danny Trejo voices Raul Tejada, Jason Marsden voices Craig Boone, William Sadler voices Victor and Ron Perlman returns as narrator.

How these pages connect

Each major character dossier links back to this cast guide. As dedicated voice-actor profiles are added later, this hub can become the bridge between game characters, actor careers and other Fallout appearances without duplicating biography text across dozens of pages.

Credits and attribution

Use in-game credits and reliable cast databases for role attribution. When adding actor photos, use licensed press photography or media you have permission to publish rather than copying headshots from entertainment databases.

Major performances to recognize

Fallout: New Vegas uses a large cast, but several performances became inseparable from their characters. René Auberjonois voices Robert House with controlled, patrician certainty; Matthew Perry gives Benny a slick casino cadence; John Doman makes Caesar sound more like a persuasive political operator than a shouting warlord; Dave Foley turns Yes Man’s compulsory helpfulness into comedy with an edge. Those four voices sit near the main faction conflict, so players hear very different styles of authority as they decide who should control the Mojave.

Companions add another cluster of recognizable performers. Jason Marsden voices Craig Boone, Felicia Day voices Veronica Santangelo, Zachary Levi voices Arcade Gannon and Danny Trejo voices Raul Tejada. Their work matters because companion stories contain long conversations that can shift from jokes to trauma without a cinematic cutscene carrying the emotion. The acting has to make those changes believable while the player is still standing in an ordinary game environment.

Narration, radio and the sound of the wider Mojave

Ron Perlman continues the franchise’s narration tradition, framing the game with the familiar “war never changes” perspective while the actual story spends dozens of hours showing how differently groups respond to that history. Wayne Newton voices Mr. New Vegas, whose smooth radio presence helps make the Mojave feel inhabited even when the Courier is crossing an empty stretch of desert. Radio announcements also react to events, giving the player a sense that major choices are becoming public stories.

The voice-cast page is designed as a navigation hub rather than a replacement for full credits. Each major character file links back here, while the page can grow as Vault-Tec.com creates voice-actor profiles with verified career information. That avoids publishing dozens of thin actor pages whose only useful fact is a single game credit.

Credit accuracy and cross-media distinctions

Game voice actors and television performers should never be conflated simply because they portray the same character. Robert House is the clearest current example: René Auberjonois voices House in New Vegas, while Justin Theroux portrays the character in the Prime Video series. The Game Archive links to the cross-media character dossier so readers can move between versions without implying that the credits are interchangeable.

For lesser roles, the archive should verify credits against the game’s official credits and reliable databases before creating a standalone profile. A cast hub can list a performer accurately with much less risk than an invented biography page. When a voice actor eventually receives a dedicated article, that page should add career context, other Fallout roles where applicable, sources and links back to every character or game file that justifies its existence.

Decisions worth noticing

New Vegas mixes celebrity casting with performers who carry companions and faction leaders across many hours of optional dialogue. New Vegas — Wayne Newton.

Credits matter because several actors are strongly associated with one role while others perform numerous minor characters, radio voices or ambient parts.

What becomes clearer later

A cast guide becomes more useful when it links performances to the quests where the character has meaningful material instead of functioning as a detached name list.

Keep René Auberjonois’s game performance of House distinct from Justin Theroux’s television portrayal, and use the character dossier as the bridge between them.

The cast works best as an index of performances rather than a celebrity list. René Auberjonois gives Mr. House a controlled, patrician authority; Matthew Perry makes Benny sound smooth until his plan begins slipping; John Doman gives Caesar the confidence of someone accustomed to being obeyed; and companions such as Veronica, Arcade and Raul gain much of their personality from Felicia Day, Zachary Levi and Danny Trejo. Wayne Newton’s Mr. New Vegas and Ron Perlman’s narration sit outside the companion-and-faction structure, but they help define the game’s voice just as strongly.

Following the cast through the quests where those performances matter turns a credit list into a useful character reference.

It also gives readers a direct path from performer to character and back again.

For returning players, the index can also resolve familiar voices that are easy to recognize but hard to place. That makes it useful both as a cast reference and as a bridge into character, faction and companion pages.
