The early reviews are in on James Spader's performance on "The Office" - and at least one of his co-stars is a big fan.

"James Spader is killing it!!!" Rainn Wilson - who plays neurotic salesman Dwight Schrute on the hit NBC sitcom - Tweeted on Thursday afternoon.

As previously reported on AccessHollywood.com, Spader has joined the cast as new Dunder Mifflin branch manager Robert California, who quickly ascends from his branch position to CEO of the office's parent company, Sabre.

Rainn has previously expressed his admiration for the incoming veteran actor, who joined the cast for a cameo in the season finale last year before joining the show full-time.

"I got to do some scenes with, really, a hero of mine, James Spader, who is, I think, one of America's greatest actors," Rainn told Access back in May around the time of the season finale, offering a forecast of what could be to come between Dwight and Spader's character. "[He's] a really confident kind of savant business manager type and he just really rubs Dwight the wrong way so they have these power battles."

Steve Carell - who played the iconic yet bumbling branch boss Michael Scott before leaving near the end of last season - also offered his approval of his replacement.

"I think it's an excellent choice," Steve told Access earlier this month. "I think it's great and he will infuse all this new energy into the show."
