Tomorrow, When the War Began star Caitlin Stasey doubts she will reprise the lead role of Ellie Linton in any sequel.

Although production company Omnilab remains committed to filming the second book in John Marsden’s best-selling teen franchise, the 21-year-old actress fears the original cast members will be too old to play the teenage characters by the time it finally goes into production.

"You always hear things, you always hear that someone's writing it, that someone's putting it together," Stasey told IF magazine.

"Nothing has happened until it happens. Unfortunately for the Tomorrow series, I feel that for the actors that were in the first film, maybe our commitment to it is done."

The apocalyptic action adventure, about a bunch of teenagers who turn into rebel fighters when their country is invaded by a foreign army, was the highest-grossing Australian film of 2010, taking $13.48 million at the box office. But it failed to secure a US distributor.

A sequel was to start filming in February last year, with Tomorrow When The War Began writer-director Stuart Beattie at the helm.

But the project was shelved when he signed on to write and direct a film adaptation of the graphic novel adaptation I, Frankenstein, now shooting in Melbourne with Aaron Eckhart in the lead role.
