John Krasinski, who portrayed Jim Halpert, told PARADE that "the show gave (him) everything."

"I was a waiter before I got it, and it's given me every opportunity," Krasinski told PARADE. "I wouldn't have met my wife (Emily Blunt) if it wasn't for the show because I wouldn't be in L.A. being an actor. There's so much that this show has given me that it will forever be the defining thing in my career no matter what, and I'm really proud of that."

NBC also posted several videos on its website that feature the cast's looking back on the show's run in a series called "The Office Farewells."
