Atlantis' Joe Flanigan, BSG stars to guest on Warehouse 13

Stargate Atlantis star Joe Flanigan will appear in SCI FI Channel's upcoming Warehouse 13, as will former Battlestar Galactica cast members Tricia Helfer, Michael Hogan and Mark Sheppard, SCI FI announced.

Other guest stars include Gossip Girl's James Naughton; Roger Rees of Cheers; Eureka's Joe Morton, Erica Cerra and Niall Matter; and Ivan Sergei from Crossing Jordan.

In the show, two Secret Service agents (Eddie McClintock and Joanne Kelly) find themselves abruptly transferred to Warehouse 13, a massive, top-secret storage facility in windswept South Dakota that houses every strange artifact, mysterious relic, fantastical object and supernatural souvenir ever collected by the U.S. government.

The Warehouse's caretaker, Artie (Saul 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.

Following is a rundown of the guest spots

♦Sergei will play Ross, an EMT from Unionville, N.Y. Ross and some of the other townspeople begin to display bizarre behavioral symptoms—involuntary (and potentially dangerous) expressions of their subconscious desires.

♦Helfer 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.

♦Flanigan portrays the handsome and 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.

♦Naughton is Gilbert Radburn, a well-tailored, high-profile entrepreneur. When a competitor threatens his intended acquisition, Radburn's suspicious behavior brings him under Pete and Myka's scrutiny.

♦Rees 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.

♦Cerra and Matter portray Jillian and Gary Whitman, small-time thieves on the Las Vegas strip whose fortunes, twisted by the strange power of a luck-inducing artifact, take a fantastic turn.

♦Morton stars as John Hill, a charismatic inmate and extremist religious leader in a Florida prison.

♦Sheppard 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.

♦Hogan portrays Myka's father, Warren Bering, who receives a dangerous object anonymously in the mail that puts his life in jeopardy. Hogan's real-life wife, Susan, will play Myka's mother.

CCH Pounder, who appears in the pilot, returns in a guest-starring role as Artie's boss, Mrs. Frederic. Warehouse 13 will premiere July 7 with a two-hour pilot at 9 p.m. ET/PT.
