When BoJack Horseman premiered on Netflix in 2014, viewers expected an offbeat adult cartoon. What they got instead was one of the most emotionally complex, culturally impactful, and critically acclaimed animated series ever created.
From trauma and generational pain to addiction, loneliness, fame, and recovery, BoJack Horseman explored topics that few animated shows dared to touch. But one of the biggest reasons the series resonates so deeply is because of its exceptional voice cast.
Each actor brought humanity, nuance, and emotional truth to their role — turning anthropomorphic characters into fully realized individuals with internal conflicts, dreams, and flaws.
This pillar guide explores every major cast member, their performances, what they contributed to the show, and why this ensemble remains one of the strongest in modern animation.
Main Cast of BoJack Horseman
The series features a powerhouse combination of comedic actors, dramatic performers, and Hollywood legends.
Below is a complete brakdown of the main cast, their roles, and the emotional weight they brought to the series.
Will Arnett as BoJack Horseman
Will Arnett voices the show’s troubled protagonist — a washed-up 1990s sitcom actor drowning in guilt, self-sabotage, and addiction.
Why Arnett’s performance is iconic
- His gravelly, tired voice perfectly embodies BoJack’s cynicism, regret, and self-loathing.
- He balances dark humor with emotional vulnerability in ways few animated performances ever have.
- Arnett voices two versions of BoJack — the sarcastic exterior and the deeply wounded internal monologue.
- Critics consistently cite BoJack as Arnett’s most powerful role.
Fun Fact:
Arnett originally worried he wasn’t “funny enough” for the role — but his performance became the emotional core of the series.
Amy Sedaris as Princess Carolyn
Princess Carolyn — BoJack’s longtime agent, manager, and former partner — is voiced brilliantly by Amy Sedaris.
Performance strengths
- Sedaris’ rapid-fire comedic delivery matches PC’s frantic professional life.
- She expresses Princess Carolyn’s resilience, heartbreak, ambition, and loneliness with subtle emotional depth.

Why it matters

Alison Brie as Diane Nguyen
Diane is a whip-smart ghostwriter, political thinker, and BoJack’s emotional counterpart. Alison Brie’s voice acting brings intellectual sharpness balanced with quiet sadness.
Why Brie’s interpretation is praised
- She captures Diane’s thoughtful, moral, often overwhelmed personality.
- Her tone shifts in moments of depression and self-discovery add realism.
- Brie portrays Diane’s struggles as a writer, a partner, and a woman examining her purpose.
Diane remains one of the most relatable characters because Brie plays her without exaggeration — only honesty.
Aaron Paul as Todd Chavez
Aaron Paul voices Todd Chavez, the lovable, directionless couch-crasher who becomes one of the show’s most emotionally grounded characters.
Why Aaron Paul is perfect for Todd
- Brings youthful energy, warmth, and comedic timing.
- Creates emotional contrast to BoJack’s negativity.
- Delivers Todd’s surprisingly wise moments with sincerity.
- Voice acting helped Todd evolve from comic relief into a nuanced character exploring identity, independence, and asexuality.

Tompkins’ performance
- Infectious enthusiasm and upbeat tone.
- Deep emotional resonance in scenes revealing Mr. Peanutbutter’s insecurities.
