'Conan' Ending: All the Guests Confirmed for the Final Week of Conan's TBS Show

Conan O'Brien's late-night career talk-show career began with Late Night with Conan O'Brien in 1993. After almost 30 years hosting late-night TV, O'Brien is moving to a weekly variety show on HBO Max, ending an era.

Before O'Brien's departure from TBS, he will have some brilliant celebrity guests to bid him a fond farewell.

All the Guests Confirmed for The Final Week of Conan's TBS Show

The last two weeks of Conan have seen O'Brien move from his usual set to the Largo Theater, where interviews take place in front of a live audience.

Patton Oswalt, Martin Short, JB Smoove and Mila Kunis have already appeared with O'Brien on the stage.

Upcoming guests for the final three episodes are Seth Rogen, Dana Carvey and Jack Black, with Bill Hader beginning the final week.

Carvey and O'Brien worked together on Saturday Night Live, so it may be their episode will look back over O'Brien's career from an earlier point.

Black has already released a short of him preparing for the finale, which is an hour-long special.

In the video, he said: "So Conan O'Brien asked if I would be the final guest on his final episodes of the Conan O'Brien show on TBS.

"And I was like, 'Absolutely, dude. We go back, way back.'

"It's an honor. Is it pressure? Yeah, it's a lot of pressure.

"If you think about that, if you're the final guest that means you have to be the best guest of all times.

"Am I up to the task? Hell yes. I aims to bring it."

Black then pretended to be "having a nervous breakdown" as he strived for ideas to make the finale the best episode yet.

Rehearsals for the final shows have shown O'Brien playing guitar in his band, which could suggest a potential collaboration between O'Brien and Black, if not Black's band Tenacious D.

The pair have played together on Conan before, so this could be a new opportunity to bring Kyle Gass onto the show.

According to Warner Media, the final two weeks of shows will also include "special surprise guests as well as a look-back at memorable moments of this iteration of O'Brien's historic late-night career," suggesting further celebrities could grace the Largo Theater.

O'Brien's new show is currently untitled, but has been reported by Deadline as a weekly variety show on HBO Max and is expected to arrive "in the near future."

Speaking about the new series, O'Brien announced on Conan: "The plan is to re-emerge on HBO Max sometime in the near future with I think what will be my fourth iteration of a program."

Brett Weitz, general manager of TNT, TBS and TruTV, said at the time of his announcement: "We're incredibly proud of the groundbreaking work that Conan and his team have accomplished during the 10 years at TBS and are so glad that we will continue to have his presence on our air with the Conan Without Borders specials.

"We celebrate his success and are glad to see it grow across our WarnerMedia family."

It is unclear which of O'Brien's team will also re-emerge on HBO Max, such as Andy Richter and Jordan Schlansky, though his assistant Sona Movsesian has posted an image of packing up her desk at Warner Bros, suggesting she will be moving with O'Brien to HBO Max.

Conan airs on TBS at 11/10c on June 22-24
