WhileIfwill mark Carell and Krasinski’s first professional collaboration sinceThe Office, the two reunited virtually over video chat in 2020 amid theCOVID-19pandemic to celebrate the series' 15th anniversary in a segment on Krasinski’s YouTube showSome Good News.

Krasinski said during the segment that filming the scene when Carell’s character, Dunder Mifflin Scranton branch manager Michael Scott, leaves in season 7 was “the most emotional I’ve been on set.”

Lookingback at their time together, Carell told Krasinski (who played salesperson Jim Halpert), “Some of the most fun memories, personally or professionally, are intertwined and connected with that show.”

And his former costar agreed, saying, “Without a doubt. Listen, I know everyone’s talking about a reunion, hopefully one day, we just get to reunite as people. And just all get to say hi.”

The Officedebuted in March 2005 and ran for nine seasons, concluding in May 2013. In addition to Carell and Krasinski, it also starredMindy Kaling,Rainn Wilson,B.J. Novak,Angela KinseyandJenna Fischer.

The beloved sitcom began exclusively streaming on NBCUniversal’s Peacock in January 2021, and since then, there has been some chatter about the future of the show.
