Obsessed fans of hit show Lost have caused chaos by invading the Hawaiian locations to get close to their TV idols.
Dozens of women determined to get close to the drama's male stars, including Matthew Fox and Dominic Monaghan, have interrupted filming and caused delays which have cost producers over $500,000 ($900,000).
A production source explained how making the show has become more difficult since its actors are now some of the biggest stars on television.
They said, "Things were a lot easier filming the first series when the cast were still largely unknown. But now some of them have a very enthusiastic fan base who will stop at nothing to get close to their idols.
"We may be on an isolated island but there have been several incidents where fans have stormed the set.
"It's cost about half a million in lost filming time and additional security."
