TITANIC” director James’ Cameron’s long-awaited TV series — “Dark Angel” — quietly got started this week in Canada.

The series — starring Hollywood’s new “It” girl, Jessica Alba (“Never Been Kissed”) — is one of the most closely watched TV projects of the year because of Cameron’s credentials as the creator of the biggest money-making movie of all time.

“Dark Angel” is set in a post-apocalyptic America. It follows the adventures of a genetically enhanced girl named Max who was created in a top-secret lab to be a super-soldier.

If the show lives up to its pedigree, Max could easily become TV’s next power-girl — a niche currently occupied by vampire-slaying vixen, Buffy Summers (Sarah Michelle Gellar) from “Buffy the Vampire Slayer.”

With a budget rumored to be nearly $8 million, the two-hour pilot episode is expected to be one of the most expensive television shows ever made, according to studio sources

The premise: “If the military engineered a human being that didn’t have any social or familial attachments, would that person be better in combat?” asks “Dark Angel” co-creator Charles “Chic” Eglee.

“Of course the master planners in the military don’t take into account the essential humanity of these [engineered soldiers],” Eglee added.

“When the experiment is aborted these [soldiers] end up out in the world on a quest to find each other and find out about themselves,” Eglee said.

Max, described as a complex 18-year-old girl, is genetically superior to the average human.

She escapes from the 21st century top-secret lab where she was made and is then hunted through the Pacific Northwest by her military creators.

The series is set to debut next fall on Fox.
