NEW YORK - June 14, 2011 - Three anticipated guest stars come to Syfy's hit original series Eureka this July, which returns with all-new episodes on Monday, July 11 at 8 p.m. ET/PT. Felicia Day debuts her seven episode arc on Monday, July 18 at 8:00 p.m. ET/PT. Comic book legend Stan Lee, creator of Spider-Man, makes a cameo appearance in the new episode airing Monday, July 25 at 8:00 p.m. ET/PT. Wil Wheaton returns for seven episodes during the second half of season four to reprise his role from last year as Dr. Isaac Parrish.

Ms. Day (web series The Guild, Red) 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.

Mr. Wheaton (Star Trek: The Next Generation) returns as the contentious Dr. Parrish, who is in competition with Fargo to be selected to the mission. The two also vie for the affections of Dr. Marten, who unwittingly finds herself at the center of a love triangle.

Mr. Lee portrays Dr. Lee, an expert on the effects of gamma radiation, making him a candidate for the mission.

Eureka seems like any other cozy, Pacific Northwest town, but is actually a secret community of geniuses assembled by the government to conduct top-secret research. What they've unwittingly created is a place where anything imaginable can happen... and does. Eureka stars Colin Ferguson, Salli Richardson-Whitfield, Joe Morton, Erica Cerra, Neil Grayston and Niall Matter. Co-creator Jaime Paglia and Bruce Miller are Executive Producers and the series is produced by Universal Cable Productions.
