But before his island adventure, fans knew Fox as Charlie Salinger on "Party of Five," a big brother forced to take care of his younger siblings after their parents' death. Did you know: Like his "Party of Five" costar Jennifer Love Hewitt, Fox also played a ghost whisperer. His short-lived series "Haunted" premiered in 2002 with Fox in the lead role as ex-cop turned private eye Frank Taylor. After a near-death experience activates his sixth sense, Frank works with spirits good and evil to solve his client's cases.
