^Huh? The Lost Boys was a 1987 Joel Schumacher film about teenage vampires. Or the midseason finale of Stargate Atlantis's second season. Is it possible you're misremembering the SciFi Channel miniseries The Lost Room, which had nothing remotely to do with Peter Pan but was vaguely similar to Warehouse 13 in that it was driven by the hunt for artifacts with mystical powers

What on earth does the Lost Room or Warehouse 13 have to do with Peter Pan? The Lost Boys was heavily influenced by Peter Pan. That's even where they got the title of the movie...
