Original "Dark Shadows" creator Dan Curtis and "ER" and "West Wing" producer John Wells are heading up the WB project, along with Mark Verheiden ("Smallville") who wrote the pilot, Zap2it.com reports.
If "Dark Shadows" makes it to the WB lineup, the show will join "Angel," another supernatural-theme program, though the shows differ in style.
"One is an action-adventure franchise and one is a very gothic soap opera," said Jordan Levin, co-chief executive officer of the WB.
WB executives also have encountered this situation before when the network hosted both "Buffy the Vampire Slayer" and "Angel" for several seasons before "Buffy" moved to UPN.
Joss Whedon, who created both "Buffy" and "Angel" welcomes the addition of another ghoulish program.
"Clearly, I'm the 97th guy to use the vampire metaphor to tell stories," Whedon said. "I have no problem with there being a 98th."
