30 Rock just started shooting its new season this week, and already the guest star reports are coming in. First up, Denise Richards will be coming on board for a one-episode appearance, although who she’ll be playing hasn’t been announced. Then, James Marsden has just signed on for a six-episode arc. His character details are also being kept under wraps, but I assume that he will play someone hunky. Another beau for Liz Lemon, perhaps? Or maybe a new nanny for Jack’s daughter? Time will tell!
In any case, these two will be joining the previously-announced Will Arnett as guest stars in the upcoming season, which will start airing in January.
