Wilson posted an Instagram photo with Krasinski on May 9, after the two reunited backstage at CBS Mornings.
Wilson, 58, wrote in the caption that he was there to promote his new podcast "Soul Bloom," while Krasinski was also there to promote his upcoming directorial debut in IF.
"Look who I ran into behind the scenes at @cbsmornings - @johnkrasinski is promoting @ifmovie and YOU MUST GO AND SEE IT NEXT WEEK!!!!" Wilson captioned the photo.
"It was fantastic to see my incredibly gifted, big-hearted brother from another (Scranton) life!"
Krasinski published a similar photo on Instagram, joking in the caption, "Soooo..." I guess I found my IF," referring to his future film.
Krasinski and Wilson played Jim Halpert and Dwight Schrute, respectively, on all nine seasons of The Office. The acclaimed comedy series, which aired 201 episodes between 2005 and 2013, chronicled the daily life of Dunder Mifflin Paper Company employees at their Scranton, Pennsylvania location.
The show's cast included Krasinski and Wilson, as well as
Steve Carell, Jenna Fischer, Mindy Kaling, B.J. Novak, Ed Helms, Craig Robinson, Creed Bratton, Kate Flannery, Angela Kinsey, Phyllis Smith, Brian Baumgartner, Oscar Nuñez, Leslie David Baker, Paul Lieberstein, Melora Hardin and Ellie Kemper.
Krasinski recently reunited with more than just Wilson from The Office. Carell also appears in IF, playing Blue, one of the main characters' imaginary acquaintances. "We actually worked together on this little thing a long time ago," Krasinski revealed in a behind-the-scenes video shot while the two were working on the project.
Though the IF cast also includes luminaries like Jon Stewart, Phoebe Waller-Bridge, Emily Blunt, Matt Damon, Maya Rudolph, Sam Rockwell, Christopher Meloni, Richard Jenkins, Awkwafina, and Louis Gossett Jr., Krasinski said he was very pleased to work with Carell again.
"Oh my God, The Office reunion we've all been waiting for is in it," he told Entertainment Weekly about the movie. "The truth is, Steve is one of the most gifted individuals on the globe. So, whether I'd ever worked with him before or not, I'd been shooting for him because I could hear his voice in my brain while composing Blue.
In the years since The Office's final episode aired, cast members have all voiced fond memories of the show — as well as a wish to return to the Dunder Mifflin world. Peacock announced a spinoff of the series on May 8, but no original cast members are likely to appear.
Despite this, Fischer, 50, recently told PEOPLE that the cast communicates often using a group chat called "Office Peeps."
"We all text on it, send pictures, updates, and everything else you'd expect from a text thread," the Office Ladies podcast co-host added. "We all run into each other and meet up on the side. But we have our SMS thread, which is running strong."
