Kiefer: 'It's the most powerful 24 ending ever'

Kiefer Sutherland says this season's 24 finale is going to be emotional.

"The most I can tell you about it is that it's not going to end because someone cuts two wires and the clock on the bomb stops," the actor, who plays Jack Bauer on the show, told www.parade.com.

"It is going to end with some of the characters going through a very difficult emotional dilemma which will be much more dramatic than a big action sequence. I believe that it's the most powerful important ending that we've ever had to a season."

The final episode of the show's seventh season goes out in the US in May. But fans anticipating a big screen version of the series may have to wait until the show finishes for good.

"We thought it would be kind of cruel and unusual punishment to ask the writers to script the equivalent of 12 films a year and then say, 'By the way, in your off time come up with an unbelievable idea that's so superb that we could justify making a feature film out of it?'" said Kiefer.

"So we collectively decided that when the show is finished then we would take it on.

"I like the idea of a two-hour representation of a 24-hour story, but I would like to go back and to try to make it much smaller like it was in the beginning, where Bauer's sole responsibility was to protect one guy and through that his family was placed in jeopardy."
