http://popculturezoo.com/archives/2837 broke the news today. Here's an excerpt:
We’ve just heard from SCI FI that Joe Flanigan (Stargate Atlantis) and Ivan Sergei (Charmed, Crossing Jordan) have landed guest starring roles on the new series Warehouse 13. The new original one-hour series stars Eddie McClintock, Joanne Kelly, Saul Rubinek, Allison Scagliotti and previously announced guest star CCH Pounder. The series is currently in production in Toronto and will premiere Tuesday, July 7 with a two-hour pilot starting at 9:00PM.
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.
Joe Flanigan will be playing 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.
Okay, he'll probably be the bad guy (that's my guess - I've watched too much TV) but this explains why Joe is currently in Toronto! I was going to give the series a look-see, but now WILl watch to see who else from SGA also appears.
