'The Office': Behind the scenes with Will Ferrell; plus, more guest stars!


Up above, you can get a little peek into what "The Office" with Will Ferrell will be like, as well as some behind-the-scenes footage about how Ferrell is settling into his new, temporary job.

It's good stuff (especially the part where Ed Helms admits thinking Ferrell's name was actually Ron Burgundy) -- but it's probably not the biggest "Office"-related news of the day.

That comes courtesy of TVLine, which reports that the show's season finale has added three more high-profile guest stars: Ray Romano, British actress Catherine Tate and James Spader, late of "Boston Legal." They join the previously announced Ricky Gervais and Will Arnett.

All three of the newly booked guests will play candidates for Michael's ( Steve Carell) job, but since Romano's already got a day job on "Men of a Certain Age," his character's interview isn't likely to go all that well. Multiple Emmy winner Spader and Tate -- who starred in her own, very funny BBC series and appeared in numerous "Doctor Who" episodes -- could well be in the running to join Season 8 full-time, though.

"The Office" season finale is scheduled for May 19.
