Dark Angel made a star of Jessica Alba

Alba, who was nominated for a Golden Globe TV award in 2001, plays a feisty human prototype who teams up with a cyberjournalist to battle an oppressive regime in the near future.

But despite making a star out of its lead actress, the show was not a big enough ratings success on Fox TV.

Debut

Dark Angel, which is shown on Sky One in the UK, averaged six million viewers in the US.

Cameron, who co-created the series, made his TV directing debut on what turned out to be the show's series finale, which aired earlier this month.

Sarah Michelle Gellar stars as Buffy

Four years ago his film Titanic won 11 Oscars and became the most successful movie of all time.

He has yet to announce which film he will direct next, instead concentrating on Dark Angel.

The show's Friday night slot will be filled by Firefly, a space Western from Joss Whedon, the creator of the hit franchise Buffy the Vampire Slayer, Daily Variety said.

Mr Whedon has promised a different kind of sci-fi drama with the characters being more "real" and "working class" than the average futuristic heroes.

Buffy is shown on the BBC and Sky One in the UK.
