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.

Wil Wheaton (Star Trek The Next Generation, The Big Bang Theory) reprises his role as Dr. Isaac Parrish in the second half of the season. This time around Dr. Parrish is in competition with Fargo to be selected for a mission. The two also vie for the affections of Dr. Marten, who unwittingly finds herself at the center of a love triangle.

Warehouse 13 isn’t bringing on the powerhouse geek guest stars, but the show will feature more Eureka crossover fun and some new reoccurring characters this season to go along with all of the artifact hunting. Last season’s ending left us falling from a cliff when Myka (Joanne Kelly) left the Warehouse team.

Aaron Ashmore from Smallville joins the show playing Steve Jinks, Pete’s new partner who was recruited by Mrs. Frederic (CCH Pounder). Agent Jinks has a power worthy of the relics stored at the warehouse, he can detect when someone is lying. Other than Claudia’s (Allison Scagliotti) freaky intelligence, which you may consider a special power, no other character has shown any type of special power other than those given to them by a relic so this is a new element to the series this season. We’ve also previously heard that there will be a Warehouse 13 spin-off series featuring the villain H.G. Wells from last season so we’ll probably see her at some point in this season of the show too.
