To mark the occasion, several of the cast members — along with legions of their fans — took to Twitter and Instagram to share sweet messages to each other, along with some fun behind-the-scenes photos we'd never seen before. On this day after their 10-year anniversary, we thought we'd gather some of their best.
John Krasinski went for a classic cast photo:
Rainn Wilson couldn't seem to believe the anniversary was here already:
Yes, this is a "Dundie Selfie"! It's hard to believe that 10 years ago #theoffice premiered on Nbc! What an awesome amazing journey. Thank you to all the fans for supporting us all along the way! In honor of #theoffice 10 year anniversary, I'll be taking over @yahootv with some photos I gathered from set over the years. Xoxo, Angela
Last photo I’ll share today… This photo is from "Work Bus" directed by Bryan Cranston. We parked by a park and all clumped together under some shade between scenes and this photo happened. I love these people! And thank you #theOffice fans. You are the best and none of this would have happened without you all! Happy 10th anniversary! - @angelakinsey
