Lost : the death of Jack

In one of the biggest shocks in sci-fi, Lost producers are planning to kill off Jack Shephard next year.

The castaways' mainman, played by Matthew Fox, will die in the very last episode of the hit show, according to insiders.

Show boss Carlton Cuse refuses to confirm or deny the news.

"We put a lot of time and effort into creating surprises and unexpected events in the storylines," he says.

"If you're watching Lost, it should be a pristine experience."

So will he kill off the doc?

"I wish I could answer that question," he says. "But it'd be like watching The Sixth Sense and knowing Bruce Willis is dead."

We'll take that as a 'yes' then.
