The day's top national and international news.
The addition of Spader's character, Robert California, will "cause some adjustments from the rest of the cast coming around… There's some new actors coming besides Spader," Greenblatt said at the Television Critics Association Summer Session 2011 in Beverly Hills.
When asked who was joining the cast permanently, like Spader, Greenblatt said the additions would actually be in guest star form.
"This is a playground for extraordinary actors… I think there's gonna be a few people that are gonna come and guest star as the season goes on," he said, clarifying.
As previously reported on AccessHollywood.com, Spader is rejoining "The Office" mix following his season finale appearance as California, a persuasive man who interviews for Michael Scott's job.
NBC confirmed earlier this summer that Robert will get the job and quickly move up the corporate ladder, becoming the Chief Executive Officer of Sabre, Dunder Mifflin's parent company.
"I think James Spader… is completely different than Steve," Greenblatt added on Monday of how Spader fits in the new "Office" mix. "[He has] his own iconoclastic acting style. I think the character is really unique. I think he's a really perfect fit in that mix."
