Four years after it closed its doors, "The Office" may soon be back for business again.

According to TV Line, NBC is eyeing to revive the hit comedy series that ran for nine seasons from 2005 to 2013. Citing unnamed insiders, the revival could potentially return to the Scranton Dunder Mifflin paper company branch in the 2018-2019 TV season with a mix of old and new cast.

It is unclear who exactly are returning, but Bustle predicts there may only be a few. The publication notes many of its cast has had successful post-Office careers. Mindy Kaling, who played Kelly Kapoor, is busy with "A Wrinkle of Time" and another revival, Warner Bros.' "Ocean's 8." Jim Halpert actor John Krasinski is writing and directing films like "A Quiet Place, while Ed Helms, aka Andy Bernard, has his own show, "The Fake News with Ted Nelms."

However, supporting characters like Angela (Angela Kinsey), Phyllis (Phyllis Smith), Meredith (Kate Flannery), Kevin (Brian Baumgartner), Stanley (Leslie David Baker), Oscar (Oscar Nunez), and Toby (Paul Liberstein) may likely return.

Kinsey already responded to the revival news, expressing her sincere confusion on Twitter. Apparently, she was in the dark about the revival plans. The actress urged network executives to get in touch with her to sort things out, but she once made it clear that she is in if ever "The Office" reboot does happen.

Back in October, she told US Weekly she would love to revisit "The Office" with her former costars, although there were no talks of the show's return then.

"I would love it, but I have no idea," she said. "Everybody is doing so many things, but sign me up!"

NBC has not confirmed the claim yet, so fans should not keep their hopes up. However, network president Bob Greenblatt did include "The Office" on his revival wish list prior to the relaunch of "Will & Grace." The Debra Messing- and Eric McCormack-starring sitcom has been a critical and commercial success for the network.
