(RTTNews) - Ray Romano, James Spader and Catherine Tate have all reportedly joined the growing list of guest stars set to appear in the upcoming season finale of "The Office." According to a new report from tvline.com, the trio of stars will appear alongside Ricky Gervais, Will Arnett and Will Ferrell in the one-hour season wrap up.

The increased attention is due in large part to star Steve Carell's departure before the end of the season. Ferrell will, in fact, appear in the final four episodes of the season. Various industry insiders have speculated that the final shows will be used to announce a new boss that will replace Carell's character of Michael Scott.
Carell has made continued headlines for his departure from the show and now it seems his costar Rainn Wilson may be heading for the door as well.
"I'm ready, willing, and able to move on, I'd like to go back to theater," Wilson recently told New York Magazine. "Theater is f***ing hard and time-consuming, and there's not enough time while doing 'The Office' to rehearse and run a play."
The season finale of "The Office" will air on May 19.
