Not the actors and actresses that will be playing these parts, but the characters themselves. If it's true that the outside world will now become a plot point in the show (and after seeing the two Arctic station guys and Penelope on the phone at the end of the season finale, it looks like it will be), new characters on Lost will include:

• Female, 30s, with leadership qualities
• Female, early 20s, very attractive
• Male, Latino, early 20s, handsome, mysterious quality

So who do you want to see in these roles?
