Will Ferrell Debuts as New Boss on 'The Office' (Videos)

Two new clips have hit the web of Will Ferrell making his debut on NBC's The Office.

The actor plays DeAngelo Vickers, the new boss at Dunder-Mifflin's Scranton, Pa., branch. Vickers is (temporarily?) taking over for Steve Carell's Michael Scott, who in the previous episode became engaged to Holly (Amy Ryan) and announced he was moving with her to Colorado.

Ferrell has signed on for a multiepisode arc on the comedy and is scheduled to make his last appearance in the season finale.

Ricky Gervais, Will Arnett, Ray Romano, James Spader and Catherine Tate also will make appearances in the hourlong finale, which airs in May.
