In season one Eliza Coupe plays head flight attendant Rosa in two episodes, in season 2 when Rosa returns she is now played by Erinn Hayes as Coupe was unable to return. When her character returns Owen looks at her with slight confusion to which she replies 'What, you don't recognize me?' to which Owen responded 'You look...different'.
The first season was filmed in Puerto Rico while the second was filmed in Fiji.
"Wrecked" plays as an amalgamation of three different television series: "Lost", "Gilligan's Island", and "Police Squad", with the actors playing out the absurd situations (most of which they unwittingly create themselves) and dialogue completely straight.
In the pilot Florence is seen without wearing glasses, however every episode since she is never seen without them. Strangely in season two we find out that Pack, who has always worn glasses, only wears them as fashion function due to his boss forcing him, saying his face 'looks dumb' without them. Later in the same episode he throws his glasses in the ocean claiming he no longer needs them after having a small self-finding moment earlier in the day.
The characters full names are Owen O'Connor, Daniel 'Danny' Wallace, Todd Hinkle, Pack Hara, Steve Rutherford, Florence Bitterman, Jess Kato, Emma Cook, Karen Cushman, and Chester 'Chet' Montgomery.
