Lost

Josh Holloway was trying to cover up his Southern accent while shooting several of his first scenes in the first season. It wasn't until producer J.J. Abrams told him that the reason they cast him was BECAUSE of his accent that Holloway changed it. There are still some scenes left in the pilot where he doesn't use his Southern accent.

Andrea Gabriel (Nadia) and Lillian Hurst (Carmen Reyes) are the only performers that appear in every season but never on the island.

Jon Hamm auditioned for the role of Jack Shephard.
