Sources confirm to TVLine exclusively that three additional names have been added to the long list of potential replacements: Ray Romano, James Spader and British funny lady Catherine Tate!
The one-hour episode will air May 19, have Gervais appearing on the show for the second time, and has Arnett appearing for the first time. Also, that there will be other notable guest stars as well.
SPOILER ALERT -- Read at your own peril...this actually leaves more questions than answers. TV Guide's Ausiello hints at what might be happening on the season finale.
