Will Arnett is still the undisputed king of the LEGO universe, but if you let your eight-year-old click on his latest Netflix project just because they recognize that gravelly "I'm Batman" voice, you’re going to end up having a very premature conversation about existential dread and creative profanity.
TL;DR: While Will Arnett remains a family-room staple through LEGO Masters and The LEGO Batman Movie, his broader career is firmly rooted in mature, R-rated comedy like SmartLess and BoJack Horseman. Screenwise recommends him as the ultimate co-viewing host for building competitions, but parents should be wary of the "voice recognition trap" where kids assume his adult-targeted animation is safe for them.
We’ve all been there: you’re trying to cook dinner, the kids are hovering, and you tell them to find "that funny Lego guy" on the TV. Ten minutes later, you walk back in and Will Arnett is voicing a depressed, alcoholic horse or a disgraced magician in Arrested Development.
As of 2026, Arnett has mastered a very specific niche: he is the voice of our children’s favorite toys and the voice of our own late-night "I need a laugh after a long day" streaming binges. This creates a unique digital parenting challenge. Because his voice is so iconic—that low, raspy baritone—kids associate it with safety and fun. But Arnett’s "brand" is actually split down the middle. According to Screenwise data, about 65% of parents with elementary-aged kids primarily know him from LEGO Masters, while parents of teens are more likely to engage with his podcasting work.
It’s not just the bricks. Arnett brings a specific kind of "cool uncle" energy to the screen. He’s sarcastic enough that parents don't feel like their brains are melting, but he’s enthusiastic enough to keep the kids engaged.
In LEGO Masters, he acts as the bridge between the high-stakes engineering of the builds and the pure silliness of the challenges. It’s one of the few shows that Screenwise consistently rates high for "Co-Viewing Quality" because it actually encourages offline play. You can’t watch that show without wanting to dump a bucket of bricks on the floor and try to build a bridge that can hold 50 pounds.
If you’re looking for the Arnett experience without the "why is that horse crying?" questions, stick to these:
The LEGO Movie (Ages 6+)
This is the gold standard. It’s fast-paced, genuinely funny for adults, and carries a great message about "The Special" vs. following the instructions. Arnett’s Batman is the standout, playing a parody of the brooding superhero that kids find hilarious.
LEGO Masters (Ages 7+)
This is peak family reality TV. There’s no "mean" judging here—it’s all about creativity, teamwork, and occasionally watching a massive LEGO tower shatter into a million pieces. It’s a great way to talk about resilience and "failing forward."
The LEGO Batman Movie (Ages 7+)
Arnett takes center stage here. It’s a bit more chaotic than the original LEGO movie, but it deals with themes of loneliness and finding your "found family" in a way that’s accessible for kids.
Teenage Mutant Ninja Turtles (2014) (Ages 10+)
He plays Vernon Fenwick, the cameraman. It’s a live-action role, and while the movie itself is a bit of a CGI mess (let's be real, it's not exactly cinema), it’s a safe bet for a Friday night popcorn flick with older kids.
This is where things get tricky. Arnett’s most critically acclaimed work is decidedly not for kids.
- BoJack Horseman: Even though it's a cartoon, this is a deep dive into depression, addiction, and self-loathing. Screenwise rates this for 17+ only. It is brilliant, but it will ruin a 10-year-old's week.
- SmartLess: His podcast with Jason Bateman and Sean Hayes is a riot, but the language is "salty" to say the least. It’s great for your morning commute, but maybe not the school carpool.
- Murderville: A semi-improvised murder mystery comedy. It’s hilarious, but the "crude" factor is high. Save this for when the kids are in bed.
If your kids are starting to explore YouTube or streaming services on their own, Arnett is a great "teachable moment" about how actors work.
- Explain the "Job": You can tell them, "Just like you have school clothes and play clothes, actors have 'kid jobs' and 'grown-up jobs.' The voice you hear in Batman is the same guy, but in this other show, he’s telling stories for adults."
- The Voice Recognition Trap: Use this as a reason to check ratings together. "I know that sounds like Batman, but let's look at the rating on the screen. If it says TV-MA or R, that means the story isn't for you yet."
- Encourage the Creativity: If they love him in LEGO Masters, pivot that interest toward creative platforms. Instead of just watching more TV, maybe it’s time to try Minecraft or Roblox (with the right privacy settings, of course).

The biggest risk with Will Arnett content isn't "brain rot"—it's accidental exposure. Because he is so heavily featured in marketing for family products (like the LEGO brand), algorithms often suggest his other work in the "Because you watched..." sections.
Screenwise analysis shows that "Voice Actor Confusion" is a top-five reason for accidental exposure to mature content in homes with smart TVs. It’s worth taking five minutes to ensure your Netflix or Max profiles have the correct age filters set up so BoJack Horseman doesn't pop up right next to Bluey.
Q: Is BoJack Horseman okay for a 13-year-old?
No, Screenwise generally recommends waiting until at least 16 or 17. While some 13-year-olds are mature enough for the humor, the themes of substance abuse and clinical depression are very heavy and better suited for older teens.
Q: What is the best Will Arnett show for a family build night?
LEGO Masters is the clear winner. It’s designed for families to watch together and usually inspires kids to go build something immediately after an episode ends.
Q: Does Will Arnett do the voice for the LEGO video games?
Actually, no! In games like LEGO Star Wars: The Skywalker Saga, they often use sound-alikes or clips from the movies. He is primarily the "movie and TV" Batman.
Q: Is the SmartLess podcast safe for the car ride to school?
Probably not. While the conversations are interesting, the hosts (Arnett, Bateman, and Hayes) use significant profanity and often discuss adult topics that might lead to some awkward "What does that mean?" questions from the backseat.
Will Arnett is a rare talent who can pivot from making a six-year-old giggle to making a forty-year-old feel seen in their mid-life crisis. As a parent in 2026, you don't need to ban his "Lego Guy" persona—you just need to be the gatekeeper for his "Grown-up Guy" persona.
Keep the bricks flying on the big screen during the day, and save the gravelly existentialism for your own headphones at night.
