Guest stars can be a good thing... or a bad thing. Some shows handle it better than others, incorporating the usually familiar stars into the episode(s) for maximum effect. The recent turn by Robert Wagner on 'NCIS' was an example of a terrific guest appearance.

Speaking of Robert Wagner, you're probably aware that he starred on the much-loved ABC's romantic detective series 'Hart to Hart' with Stephanie Powers. Now, two other stars will be playing a 'Hart to Hart' type of couple on a current show. Swoozie Kurtz and Fred Willard will be on 'Chuck' later this season as a pair of former spies who were romantically involved. 'Hart to Hart' was mentioned in Michael Ausiello's scoop, and he even went so far as to suggest a spin-off.

Joss Whedon fans, take note ... you may have competition from the fans of ABC's Pushing Daises. That's the way it seemed at their Comic-Con panel on Saturday afternoon. They were so loud and applauded so frequently that it made an audience of Whedon fans seem like a group of cloistered monks taking a vow of silence.

But, that really isn't surprising since the show (whose first season comes out on standard DVD and Blu-Ray on September 16th) has such a wealth of talent both on and off screen. The audience at the Pushing Daises panel had an opportunity to see all that talent in one place as the entire cast joined creator Bryan Fuller and executive producer Barry Sonnenfeld in answering questions about season two. The tantalizing morsels appear after the jump.
