Why John Krasinski Admitted He Had to Apologize to David Letterman Over the Ending of 'The Office'

Keeping plot points of a major TV show or movie series a secret is certainly important, and some studios take spoiler secrecy to the next level. Take the Marvel Cinematic Universe or Star Wars for instance—many of the cast members didn't even know what happened in Avengers: Endgame after they shot the film, and Luke Skywalker actor Mark Hamill compared filming the latest Star Wars trilogy to being in the C.I.A. Clearly, it's important to keep an upcoming project under wraps, and while stars of The Office weren't faced with quite as strict rules as other mega franchises, they did have to lie here and there to the media.

John Krasinski recalled back in 2013 how the cast had to keep Steve Carell's return as Michael Scott in the series finale a secret, admitting to People, "It was so thrilling. We all just flat-out lied." Where and to who did the actors do all this lying? One example is apparently when Krasinski appeared on The David Letterman Show ahead of the show's conclusion.

"I lied to Letterman! I have to apologize to him for that at some point," Krasinski told People. "It was just one of those things that we all vowed and had to protect." To see the interview he was referring to, watch below, in which he gives the host a hard "no" when asked if Carell would be in the finale.

In the throwback interview with People, Krasinski also reflected on life after the show, explaining:

"It’s really weird – it’s a whole lifestyle change. The Office has given me everything. I was a waiter when I got the show; I was 23 years old. A decade of my life! Not only has it given me every opportunity in the business, but I wouldn’t have met Emily [Blunt]. In a very big, existential way it’s the most important thing in my life."

Luckily for Krasinski, his career only got more successful after The Office, and he ended up directing the Academy Award nominated horror film A Quiet Place, followed up by writing and directing its sequel. We're sure by now, the actor has gotten used to telling a few fibs when it comes to avoiding spoilers. And if not, joining the MCU like he's been rumored to be will definitely do the trick.
