Kenan Thompson’s Bricklebaum in The Grinch: Voice Acting, Holiday Cheer, and Character Craft

Kenan Thompson’s performance as Bricklebaum in Illumination’s 2018 film The Grinch is loud, relentless, and overflowing with cheer — so much so that even Thompson has admitted the character’s nonstop enthusiasm could wear him out. Drawing from decades in sketch comedy and years of family-friendly work, he built a neighbor who is the emotional opposite of the Grinch: endlessly optimistic, socially fearless, and almost aggressively welcoming. This blend of comedy, sincerity, and sheer stamina reveals a lot about how animated characters are created, and why holiday stories resonate so strongly with both kids and adults.

Bricklebaum: The Neighbor Who Refuses to Take a Hint

Bricklebaum is a new character created specifically for the 2018 animated adaptation of Dr. Seuss’s classic, not part of the original book or the 1966 TV special. He’s the Who who lives closest to the Grinch and is convinced — against all evidence — that they are or will be best friends.

Instead of treating the Grinch with suspicion or fear, Bricklebaum behaves like an enthusiastic host who never stops inviting the grumpy neighbor to join in.

• Unshakable optimism: He assumes the Grinch is secretly a softie, no matter how rude or distant the green recluse may be.
• Relentless friendliness: He extends invitations, compliments, and small talk even when the Grinch clearly wants to be left alone.
• Holiday super-fan: Bricklebaum embraces the over-the-top decorating and celebrations that drive the Grinch mad, embodying the Whos’ maximalist Christmas spirit.

In many ways, he represents the emotional pressure of the holidays — the expectation that everyone be cheerful and social — taken to its comic extreme.

Kenan Thompson’s Comedy Background Shapes Bricklebaum

Thompson’s approach to Bricklebaum is rooted in his long career in sketch comedy and family entertainment. He joined Saturday Night Live in 2003 and has become the show’s longest-tenured cast member, known for big characters, precise timing, and committed physicality. That skill set translates naturally to animation, where exaggerated voices and clear emotional beats are essential.

In interviews around the film’s release, Thompson described Bricklebaum as an “excitable” character whose energy always had to stay high, while still feeling warm rather than abrasive. That balance — big but not grating — is something sketch comedians constantly refine. His background also primed him to adapt quickly:

• Improvisational instincts: Years of live TV sketches taught him to try variations until he hit the right tone.
• Vocal flexibility: Thompson has voiced multiple animated characters and side roles, requiring distinct, sustainable voices.
• Audience awareness: Because he has worked extensively in children’s and family content, he understands what plays for both kids and parents at the same time.

Why Bricklebaum Was So Exhausting to Play

Animated characters who live at a constant emotional peak can be surprisingly draining for the actors behind them. Thompson has described the Bricklebaum voice and performance as intensely upbeat, requiring him to sustain a high level of excitement through multiple recording sessions. Unlike a single live performance, voice acting often means recording the same lines repeatedly to give animators material to match and to satisfy directors’ notes.

Industry interviews with voice actors and directors explain why this kind of role takes a toll:

• Animated performances are usually recorded alone in a booth, which means actors must generate all the energy and emotional contrast without another performer to bounce off.
• Characters that yell, laugh loudly, or sustain big emotions can strain the voice, especially over long sessions.
• Directors may request many small variations — faster, slower, happier, more frantic — consuming both vocal and mental energy.

Research on occupational voice use notes that professional voice users (like actors and singers) face a higher risk of vocal fatigue, hoarseness, and overuse injuries if they do not manage rest and technique carefully. For a relentlessly upbeat character like Bricklebaum, that risk is amplified, especially when the tone must stay bright and clear.

The Craft of Voice Acting in Animated Holiday Films

The Grinch highlights how much of an animated film’s humor and emotional impact depends on voice performance. Benedict Cumberbatch, who voices the Grinch, performs a character arc from cynical isolation to emotional openness, while Thompson stays locked in festive overdrive as a kind of cheerful counterweight.

Creating that effect involves several layers of craft:

Directors often record actors on video during sessions, then give animators the footage so they can incorporate subtle facial expressions, posture, and timing into the character’s final form. That process helps explain why Bricklebaum’s movements and expressions feel so closely tied to Thompson’s own comedic style.

Holiday Excess, Community, and the Grinch’s World

Bricklebaum is not just comic relief; he also embodies the film’s ideas about community and holiday culture. The Whos in this adaptation expand Christmas celebrations every year, making them “bigger, brighter and louder,” which pushes the Grinch to decide he must steal the holiday to find peace and quiet.

Through Bricklebaum, the film explores both the charm and the pressure of large-scale festivities:

• Hospitality taken to extremes: Bricklebaum’s endless invitations and decorations showcase the best intentions behind community celebrations, but also how they can feel overwhelming to introverts.
• Persistent goodwill: Even after repeated rebuffs, he never becomes bitter or suspicious of the Grinch.
• Emotional contrast: His joy highlights just how isolated and defensive the Grinch has become, making the eventual transformation more satisfying.

Psychologists note that social connection and shared rituals can strongly support emotional well-being, especially around holidays. At the same time, people who are lonely or stressed may experience holiday cheer as a painful reminder of what they lack. Bricklebaum sits right on that line: he is the embodiment of communal joy for the Whos, but a constant irritant for the Grinch — until the Grinch is finally ready to accept connection.

What Parents Can Learn From Bricklebaum’s Big Energy

Parents watching The Grinch with kids may recognize Bricklebaum’s type immediately: the neighbor, relative, or friend who is always “on,” always planning the next party, always adding another strand of lights. That kind of character can be delightful on screen and challenging in real life — and many parents may notice that their own children sometimes behave like mini-Bricklebaums when excitement runs high.

Several ideas from child development research can help parents interpret and channel that big energy:

• High arousal is normal during holidays: New routines, treats, and special events can amplify kids’ emotional intensity.
• Enthusiasm can mask anxiety: Over-the-top cheerfulness may occasionally hide nervousness about social situations or family dynamics.
• Clear boundaries reduce conflict: Just as the Grinch’s discomfort is real, kids and adults sometimes need gentle limits on noise, invitations, or activities.

Parents can use Bricklebaum as a conversation starter:

• Ask kids how they think the Grinch feels when Bricklebaum shows up uninvited.
• Talk about how to be friendly while still respecting someone else’s space.
• Discuss whether there are times when they themselves feel like the Grinch, and what helps in those moments.

Kenan Thompson’s Place in Modern Family Entertainment

Thompson’s portrayal of Bricklebaum is part of a broader career in which he has repeatedly bridged the gap between children’s entertainment and adult comedy. Beyond The Grinch, he has provided voices for family-focused films like Space Chimps and Trolls World Tour, alongside his ongoing adult-skewing sketch work. This dual track gives him a unique ability to deliver humor that feels safe and playful for kids but still sharp enough to amuse parents.

His success on Saturday Night Live has also made him a familiar, trusted presence, especially for audiences who grew up watching him on earlier shows and are now watching films like The Grinch with their own children. That continuity adds an extra layer of nostalgia to his animated roles.

Behind the Scenes: The Long Road to a Simple Laugh

On screen, Bricklebaum’s jokes land quickly and feel effortless. Off screen, the process is slow and meticulous. Animated features like The Grinch typically require years of development, from early storyboarding to final rendering, with voice recording occurring in multiple passes throughout production.

For actors like Thompson, that means:

• Recording early scratch tracks that help shape the rhythm and tone of scenes.
• Returning for new dialogue as storyboards evolve or jokes are rewritten.
• Adjusting line readings to match timing changes in the animation.

That iterative process is one reason even a single energetic character can leave an actor feeling spent — the performance is not one continuous outburst but dozens of small, precisely calibrated bursts over time.
