Will Toale out Justin Hartley in as Aquaman

Keeping secrets in Hollywood is tough. Just ask Amy Sherman-Palladino, creator of the WB series Gilmore Girls. She and the rest of the cast and crew of her show were caught off guard when it was announced back in January that the WB and UPN would fold in the fall and be merged into the CW. She thought that both network heads Les Moonves and Bruce Rosenblum should be running some sort of intelligence agency in Washington for keeping the lid on this story for so long (as both networks had begun discussion about this merger as early as Thanksgiving).

She also knows how fast things can change. While Gilmore Girls will be one of the shows to survive the merger, she is unsure of its future beyond the 2006-07 season, the shows seventh year. Before the breakup, she and her husband had been working on a new show to debut in the fall, but because of new changes, one the first things to get dropped was her new development deal with the WB.

Meanwhile, another show in development at the WB and should survive the tansistion to the CW will be Aquaman, from the Smallville creators Al Gough and Miles Millar. The series was pitched to the WB last fall when American Idol contestant Alan Ritchson played him on episode of Smallville. The ratings went up, and so it was thought a great spin-off could be launched.

Back on January 9, the WB announced that former Ambercromibe & Fitch model (which must be a prerequisite for working on the WB) Will Toale was cast as the fish guy.

But as quickly as the WB becomes the CW, Toale has been replaced by Passions hunk Justin Hartley, who will now play A.C. Curry/Aquaman.

CBS Corp. president and chief executive Leslie Moonves, who is known for his interest and savvy in pilot casting decisions, weighed in on the matter and recommended that they seek a new star, though Toale was still said to be in the running to keep the role as of last week. But after some testing, it became apparent that Hartley was going to move on up to the starring role.

And while the age old decision to replace Toale was "we wanted to take the role in a different direction" may be code for some one who has more experience. Hartley has more on-camera experience than Toale, having played Nicholas Foxworth Crane on Passions for three-plus years beginning in 2002. He earned a Soap Opera Digest Award nomination for his work last year. Toale's previous credits include cameo in the feature film Uptown Girls and the 2004 TV movie Tempting Adam.

Earlier this week, Ving Rhames (Mission: Impossible III) and former Miss Universe Denise Quinones were added to the pilot, which will follow a twentysomething Curry as he begins to discover his true heritage.

Secrets and Mystery cast changes.

Just another day in the wacky world of Hollywood.
