The cast of Syfy’s hit TV show Eureka talked about what to expect in season 4.5 during a panel discussion on Friday at San Diego Comic-Con 2011.

Prior to the cast coming out, the network showed a trailer for the upcoming episodes, which revealed plenty of guest stars. The main draw of the season is definitely the appearance of Stan “The Man” Lee, creator of classic Marvel characters like Spider-Man, X-Men, The Incredible Hulk, and several more.

“We’re all very professional adults on the set… but when we did that episode with Stan Lee everyone reverted to age 12,” said Wil Wheaton, who moderated the panel and appears on the show as Dr. Isaac Parrish.

The panel featured Colin Ferguson (Jack Carter), Salli Richardson-Whitfield (Allison Blake), Neil Grayston (Douglas Fargo), Felicia Day (Dr. Holly Martin), and executive producers Jaime Paglia and Bruce Miller. We’ve embedded video of the panel below (check back soon for our one-on-one video interviews with Ferguson and Day).

It’s hard to believe, but this summer actually finds a three block of intriguing TV on Syfy Channel! Sure Alphas is an unknown entity but it’s at least worth a look. The Monday night block starts off with Eureka and Warehouse 13. The fun starts July 11th at 8/7c.

Check out these early preview clips here below and get ready for fun summer TV!

Amongst all the Mega this and Giant that of the Syfy Saturday movies the network also has some pretty great television series. Two of those shows, Warehouse 13 and Eureka, are coming back for new seasons on July 11, 2011. To whet your appetite for the premieres we have some information about the upcoming seasons of these shows along with a couple of advance preview clips from their premieres.

Eureka is bringing on the geek goodness this season with Felicia Day (Doctor Horrible’s Sing-Along Blog, Buffy the Vampire Slayer) joining the cast for a 7-episode story arc starting with the July 18th episode. She plays Dr. Holly Marten, a quirky Department of Defense visitor to Eureka tasked with evaluating eager candidates for a special mission that has been given to Global Dynamics and will pit the town’s scientists against one another.

Netflix subscribers who have been bored with the selection of streaming media available might take notice of some recent additions to their library, namely Battlestar Galactica.

But for anyone who hasn’t seen the show and has been wanting to start, don’t clear your DVD queue just yet. The first disc of the season 1 set is only available to rent as a DVD for some strange reason. This disc contains the 2-part miniseries that was created prior to being given a green light for a full season. And apparently it counts differently, except for that it’s listed as the official first two episodes of the show now.

The addition of the BSG episodes are part of a deal Netflix struck with NBC to add older content to its library, which also includes over 100 episodes of Saturday Night Live, Eureka, and much more.
