10 Surprising Will Arnett Facts For His Birthday

1. He’s the Master of Multitasking (Sort of)
Will Arnett is incredibly talented at voice acting, and that skill extends beyond just his animated roles. While many of us struggle to juggle tasks, Will has managed to balance an impressive voice acting career with his on-screen work. But here’s the kicker—he once recorded all of his lines for 'BoJack Horseman' as “BoJack Horseman” and “Batman” (yes, both characters) while on a cross-country flight. Talk about multitasking—or just pure genius. Who else could voice a depressed animated horse and a brooding superhero in one sitting? Will Arnett, that’s who.

2. He’s a Giant in the Voice Acting World
Will Arnett is the undisputed king of voice acting in children’s entertainment. You’ve heard his voice as 'LEGO Batman' in 'The LEGO Movie' and 'The LEGO Batman Movie,' but did you know that he also voices “The Gobbler” in the animated 'The Secret Life of Pets 2'? Oh, and he’s the voice behind 'Detective Jake Peralta' (yes, Brooklyn Nine-Nine fans, we’re serious) in a 2015 animated series called 'The Awesomes.' Will doesn’t just do voices, he inhabits them. If you’ve ever wished for a Batman with a dash of sarcasm, you can thank Will for that.

3. He’s an “Artistic” Chef... Sort Of
In an unexpected twist, Will Arnett has a penchant for the culinary arts, specifically when it comes to making dishes that are... let’s say memorable. He once appeared on a cooking show where he made a “pasta” dish that was more "creative interpretation" than actual food. His take on spaghetti, which he dubbed “The Special Arnett,” involved more cheese than a grocery store on pizza night. Whether it was delicious or a culinary disaster, we may never know—but it was definitely entertaining.

4. He’s Technically a D-list Rock Star
Before becoming a household name, Will Arnett had a brief (and let’s be honest, probably hilarious) stint as a musician. In the early 2000s, Will was part of a comedy rock band called 'The Wedgeheads.' Yes, you read that right. While he never quite reached 'rock star' status, the man definitely knows how to carry a tune—if by "carry a tune" you mean “mock it hilariously” in a way only Will Arnett can.

5. He’s Obligated to Make Funny Faces for a Living
Will Arnett is widely known for his facial expressions in his acting roles. But did you know that these expressions are part of a very serious "method"? Turns out, his role as 'Gob Bluth' in 'Arrested Development' required him to do so many ridiculous facial contortions that Arnett had to implement "face exercises" to prevent muscle strain. Gob might make his facial expressions seem like a natural talent, but behind that comic genius, there’s some serious muscle management going on. Who knew that funny faces require work?

6. He’s a Lover of Dogs (But with Some Serious Competition)
Will Arnett has been involved in a lot of charitable causes over the years, but none are as close to his heart as his support for animal welfare. He's a known advocate for rescue dogs, and when it comes to his own pet, he has a hilarious tale to tell: He once adopted a dog that had an affinity for digging. Not just any digging—deep digging. So, when he wasn’t busy filming 'Arrested Development', Will Arnett was playing “find the treasure” with his dog. Sure, he wasn’t actually looking for buried treasure, but let’s be real—having a dog with such high aspirations can only be amusing.

7. He’s Got a “Superhero” Side Gig
Will Arnett’s 'LEGO Batman' is one of the most entertaining, snarky versions of the Dark Knight to grace the screen. But did you know that his version of the Caped Crusader isn’t just a parody? It turns out that Will’s take on Batman has been so popular that he was asked to voice him in multiple spin-offs and other LEGO franchise crossovers. In fact, 'LEGO Batman' is probably the only Batman who would also appreciate a pizza break after a night of crime-fighting. Thank you, Will, for proving that even superheroes need a sense of humor.

8. He’s a True Gentleman—Even in Comedy
While we love Will Arnett for his dark humor and sarcastic quips, what might surprise you is how much of a gentleman he truly is. On several occasions, he’s been known to pull pranks on set, but with a twist: He’s usually the first to apologize and buy everyone lunch. Yes, even the prankster has his soft side. And let’s face it—who else could pull off a heartfelt apology with that voice and make it sound both genuine and hilarious at the same time? Will Arnett, the master of classy comedy.

9. He’s the Father of One Epic Quote
If you’ve ever watched 'Arrested Development,' you’ve likely heard Will Arnett’s character "Gob Bluth" deliver one of the most iconic quotes in TV history: “I’ve made a huge mistake.” The quote became a meme and remains a gold standard in comedic self-awareness. What many people don’t know is that Arnett improvised that line on set—and it became so iconic that even the cast members have to pause whenever they hear it in real life. Talk about creating pop culture magic!

10. He’s a Self-Proclaimed ‘Geek’
Will Arnett isn’t just an actor; he’s a geek in the best way possible. He’s openly admitted that he has a massive love for comic books, sci-fi, and all things nerdy, which makes him the perfect Batman—and the ideal voice for LEGO versions of superheroes. His enthusiasm for geek culture goes so far that he even once showed up to a press event for 'The LEGO Batman Movie' wearing a Batman suit under his clothes. If that’s not true dedication to your craft (and fandom), we don’t know what is.
