LOS ANGELES (TheWrap.com) - "The Office" series finale has been supersized.
The swan song for NBC sitcom, which airs its final episode May 16, has been extended from an hour to 75 minutes, the network said Tuesday. The "Office" series finale will now air from 9 p.m. to 10:15 p.m.
The season finale of NBC's freshman drama "Hannibal" will air after the "Office" send-off, with limited interruption.
The series finale of "The Office" will take place months after the airing of the documentary about the Dunder Mifflin paper company. Dunder Mifflin employees past and present will gather for a wedding and a final round of interviews.
"Mysteries are solved, hatchets are buried, pranks are prunked," the network said of the finale.
Guest stars for the "Office" swan song will include Mindy Kaling, B.J. Novak, Rachael Harris, Dakota Johnson, Joan Cusack, Ed Begley Jr., Malcolm Barrett, Matt Jones, Andy Buckley, Mike Schur and Bobby Ray Shafer.
