finished shooting their final episode on Saturday and ET Canada
was at the show's series wrap party getting the stars' reactions to saying goodbye to their home of the past nine seasons.
"It's time to move on to a new transition," said Rainn Wilson. But just because it's over, doesn't mean he has to like it. Wilson admitted that he's "devastated" by the show's end. "But I can't wait for all those Office reunion shows or something like that," the actor added.
Jenna Fischer likened shooting the finale to having a wedding.
"People tell you, 'It's going to go by so fast. You should try to remember every detail,'" Fischer said. "I just tried to look around the office a lot and look at people's faces and remember them, yet it still felt like I couldn't take it in enough."
Through its dominant run, The Office has weathered some major changes -- most notably, losing Steve Carell.
"When Steve left it was a little rough for us," said Fischer. "We had to find our feet again, but I think this year has just been really excellent."
Fischer, as well as the rest of the cast, seemed to love the series finale in particular.
Wilson promised, "The ending is going to blow people's minds."
The Office's hour-long send-off airs Thursday, May 16 at 9 p.m. on NBC.
