Jon Lachonis, aka "DocArzt", blogging at his UGO gig, has stated that according to his (usually very credible) sources, the world premiere beach screening event for the Season 5 has been canceled.

If you don't know what Sunset on the Beach is, it's an event put on by the City & County of Honolulu, to show free public movies on a large screen erected on the east end of Waikiki Beach. And every season of Lost (except strike-marred Season 4), ABC has hosted at this event a star-studded world premiere of the season opening episode, one week before the broadcast premiere. Think a crowd of thousands, and the cast of Lost on a red carpet. It's a great event for local fans, and it would be sad if this event didn't take place this year.
