James Spader is headed to Dunder Mifflin.

Executive producer Paul Lieberstein confirmed today that the Emmy winner will be a series regular on season eight of the sitcom.

“James will reprise his role as Robert California, this uber-salesman that has a power to convince and manipulate, like a high-class weirdo Jedi warrior,” Lieberstein said.

As previously rumored, California won't actually serve as the branch manager. Teased Lieberstein: “He’ll have been hired over the summer as the new manager, but within hours, got himself promoted. Within days, he took over the company."

Sources say the man who will replace Michael Scott in the office itself will be either Dwight, Jim or Andy.
