The Office executive producer Greg Daniels revealed on a conference call today that Season 9 will be the hit comedy series' final season. Here's what he had to say about this popular show coming to a close.

"As we head into the homestretch, we have a lot of exciting things I've been wanting to do since Season 2. The end should be pretty cool. At some point you have a choice: to always tell the beginnings of stories and the middles or to allow a story to end, and I think endings can be very powerful and meaningful pieces of the story. "If we didn't let it end this year, I don't know if we would have been able to tell the endings for so many characters that I really want to know the endings for."

Greg Daniels also announced that he will be taking over as showrunner from the departing Paul Lieberstein. He also revealed that fans will finally know the identities of the documentary crew that has been filming at the Dunder Mifflin office.

"All questions will be answered this year. We'll see who's behind the documentary, and we'll meet some of them."

When asked if Steve Carell will make a final appearance on The Office, the showrunner said that is a possibility, although the ending doesn't necessarily hinge on his involvement.

"We'll see. We have ideas for the ending, and obviously if he would participate, we would have a lot of good times. The idea will fly without him if he can't make it. He is pretty busy."

The final season of The Office will kick off its run Thursday, September 20 at 9 PM ET with the Season 9 Premiere.
