Harried anti-terrorism agent Jack Bauer could be headed to the silver screen in a "24" (search) movie.

"It could still be two years from now, so it's far too early to say," "24" director/producer Jon Cassar (search) told the Calgary Sun.

As it stands now, Cassar said the film would only partially unfold in the unique "real-time" format that's helped turn "24" into a white-knuckled success.

"The last I heard, the first hour will not be in real time," Cassar said. "But then something big will happen and real time will kick in. It still has to be worked out — it's at a stage where they really need to write it."

The script, he said, is likely to depend on what's happening on the show before the movie comes out.

On "24," Kiefer Sutherland plays (search) Bauer, a federal agent who constantly finds himself as the only one who can save the world from various nefarious terrorist plots.

Each one-hour episode of the series represents a high-octane hour in Bauer's ongoing struggle to beat the bad guys.

After three seasons, "24" has become one of the most popular dramas on television.

"The reason I think it worked is because of how it is shot and the scripts," Cassar said. "The writers are amazing — they have been able to come up with yet another bad day for Jack two years in a row."

He also attributes part of the show's success to his style of filming it. Unlike most TV and film makers who frequently yell "cut!" Cassar shoots each scene uninterrupted.

Cassar said he was shocked at first when "24" turned into a hit, almost overnight. His first impression of the series' real-time format was that it was going to be a dud.

Cassar remembers thinking, "God, that would be so boring, who's going to want to watch that?"
