SCI FI's new one-hour dramedy adventure series Warehouse 13 has confirmed an all-star lineup set to make guest appearances throughout the first season including Battlestar Galactica's Tricia Helfer, Michael Hogan and Mark Sheppard; Gossip Girl's James Naughton; Roger Rees of Cheers; Eureka's Joe Morton, Erica Cerra and Niall Matter; Stargate Atlantis' Joe Flanigan and Ivan Sergei from Crossing Jordan.

The new original one-hour series stars Eddie McClintock, Joanne Kelly, Saul Rubinek, Allison Scagliotti and previously announced guest star CCH Pounder. Produced by Universal Cable Productions, the series is currently in production in Toronto. Warehouse 13 will premiere Tuesday, July 7 with the 2-hour pilot from 9 - 11PM ET/PT.

Warehouse 13 follows two Secret Service agents who find themselves abruptly transferred to a massive, top-secret storage facility in windswept South Dakota which houses every strange artifact, mysterious relic, fantastical object and supernatural souvenir ever collected by the U.S. government. The Warehouse's caretaker Artie (Rubinek) charges Pete (McClintock) and Myka (Kelly) with chasing down reports of supernatural and paranormal activity in search of new objects to cache at the Warehouse, as well as helping him to control the warehouse itself.

Guest Stars Include:

Ivan Sergei (Crossing Jordan, Charmed) is "Ross" an EMT from Unionville, New York. Ross and some of the other townspeople begin to display bizarre behavioral symptoms -- involuntary (and potentially dangerous) expressions of their subconscious desires.

Tricia Helfer (Battlestar Galactica, Burn Notice) stars as FBI Agent "Bonnie Belski" who clashes with Pete and Myka when they interfere with a case on her Chicago turf. But after the third inexplicable bank takeover, she finds herself willing to make use of their expertise.

Joe Flanigan (Stargate Atlantis, First Monday) portrays the handsome, wealthy "Jeff Weaver" whose charm captures Myka's interest, but he finds himself under Pete and Myka's scrutiny when a sculpture on which he bid, vanishes in an impossible heist.

James Naughton (Ally McBeal, Gossip Girl) is "Gilbert Radburn," the well-tailored, Trump-esque high-profile entrepreneur. When a competitor threatens his intended acquisition, Radburn's suspicious behavior brings him under Pete and Myka's scrutiny.

Roger Rees (Cheers, The West Wing) is "MacPherson" one of Artie's former Warehouse colleagues, who has gone rogue and is now competing with the team to gather dangerous and powerful objects for his own use.

Erica Cerra (Eureka, The L Word) and Niall Matter (Eureka, The Best Years) portray "Jillian and Gary Whitman," small-time thieves on the Las Vegas strip, whose fortunes, twisted by the strange power of luck-inducing artifact, take a fantastic turn.

Joe Morton (Eureka, Terminator 2) stars as "John HIll" a charismatic prison inmate and an extremist religious leader in a Florida prison.

Mark Sheppard (24, Battlestar Galactica) is "Mr. Valda" the enigmatic representative of the Regents, the mysterious organization that controls Warehouse 13. He disapproves of Artie's methods as the team leader of the Warehouse, and isn't afraid to let him know it.

Michael Hogan (Battlestar Galactica, The L Word) portrays Myka's father "Warren Bering," who receives a dangerous object anonymously in the mail which puts his life in jeopardy.

The series is produced for SCI FI by Universal Cable Productions. It is executive produced by Jack Kenny (The Book of Daniel) who also serves as showrunner. David Simkins (Dresden Files) is executive producer; Jace Alexander (Burn Notice, Rescue Me) is co-executive producer and director of the pilot; and Stephen Surjik (Monk, Burn Notice) is producer/director of the series.
