Well looky what we have here, Rockstar apparently slipped up and let out an actor’s recruitment page. The page was posted on Actorpages by Take Two (The owners of the GTA franchise) as a private casting note.
Out of the characters only one has been identified as being legit according to the GTA Wiki:
James Pedeaston is a child molester wanted in Malaysia and is being investigated by the FBI. He hosted The Wild Traveler show on WCTR in 1992, although it is apparently syndicated to nine other stations (not heard in-game). He enjoys traveling the world and logging some of his most ‘exotic’ encounters in his travelogue, some of which he accidentally reads on-air to the disgust of the listeners. His favourite memory seems to be a relationship with a boy named Avrindar in Sri Lanka. His show appears to be so reviled by his listeners that at one point, he receives few calls which are not supportive. For example, a caller tells him to stop droning on about other countries and focus on talking about where he lives. At one point he received a phone call from a suicidal man in Verdant Bluffs who wanted to go to hell. Pedeaston replies with “Me too! Buy me a refrigerator magnet when you get thereâ€. In GTA IV, he was arrested by the Indonesian police after being suspected of child molesting in Bali, Indonesia in 2003.
