Honestly, if you were sitting in a car with John Krasinski back in 2013, you probably wouldn't have guessed you were witnessing the birth of a billion-view phenomenon. But that's exactly what happened.
John Krasinski, his wife Emily Blunt, and the legendary Stephen Merchant (co-creator of The Office UK) were just driving around, tossing out ideas for Krasinski's upcoming appearance on Late Night with Jimmy Fallon. Someone—likely John—floated the idea of a "lip sync battle." They started doing it right there in the car. It was ridiculous. It was loud. It was perfect.
Most people think John Krasinski and Lip Sync Battle are just a footnote in Jimmy Fallon’s late-night success, but Krasinski is actually the architect behind the whole thing. He didn't just perform; he built the machine.
The NBC Rejection That Changed Everything
It’s easy to forget that NBC actually said "no" to this. After the segment blew up on Fallon's show—specifically after Emma Stone’s legendary performance of "All I Do Is Win"—Krasinski, Merchant, and Fallon took the pitch for a full-length series to the network suits.
They passed.

They thought the concept was "too small." They didn't see how a three-minute segment could carry a 30-minute show. Even NBC’s sister channels, USA and Bravo, weren't interested.
Spike TV (now Paramount Network) saw the vision. They were in the middle of a rebrand, trying to move away from just being "the network for guys" and toward something broader. They took a gamble on a bunch of A-list actors pretending to sing. It became the highest-rated unscripted premiere in the network's history, pulling in 2.2 million viewers right out of the gate.
That Time John Krasinski Wore a Fringe Dress
If you haven't seen the episode where Krasinski takes on Anna Kendrick, stop everything.
While most executive producers stay behind the scenes, Krasinski got in the trenches for Season 1. He started off with a fairly "standard" boy band routine to NSYNC’s "Bye Bye Bye," complete with the headset mic and the jerky choreography. It was good. It was Jim Halpert levels of charming.

Then things got weird.
For his second round, Krasinski performed Tina Turner’s "Proud Mary." He started in a traditional suit, looking like he was ready for a board meeting. Halfway through, he ripped it off to reveal a silver, tasseled fringe dress. He didn't just "do" the song; he did the work.
The best part? Anna Kendrick fought back by serenading a montage of Emily Blunt photos while wearing a t-shirt with Blunt’s face on it. She even brought out Jennifer Lopez as a surprise guest. Krasinski lost the belt that night, but the footage of him collapsing in laughter at his wife's face on a t-shirt is the kind of authentic "celebrity-being-a-human" moment that made the show a viral powerhouse.
Why It Actually Worked
The secret sauce isn't just the music. It's the E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) of the production team. Because Krasinski and Merchant are actors with massive social capital, they could call their friends.

The show felt like a private party we were invited to watch.
- Low Stakes, High Effort: Celebrities were willing to look stupid because the show wasn't a mean-spirited roast.
- The "Theater Kid" Factor: Actors are essentially professional pretend-players. Giving them a stage, a wind machine, and Beyoncé’s discography is like giving a kid a key to a candy store.
- Viral Engineering: The show was designed for the YouTube era. Each "battle" was a self-contained, three-minute clip perfect for sharing on Facebook or Twitter.
The Legacy of the "Battle"
Krasinski’s Sunday Night Productions eventually moved on to bigger things like A Quiet Place and Jack Ryan, but the impact of the lip-sync format remains. It paved the way for a whole genre of "celebrity playtime" television.
It proved that audiences didn't want polished, PR-managed interviews anymore. They wanted to see Channing Tatum dressed as Elsa from Frozen or Anne Hathaway swinging on a wrecking ball.
If you’re looking to capture some of that Krasinski-level magic for your own content or just a weekend party, the lesson is simple: don't be afraid of the "small" idea. What starts as a silly joke in a car with friends can end up being a global franchise.
