Through out playing this game for quite a while, Ive found quite a number of Easter Eggs, some of which relate to the film. the Sierra Community Forums also has a topic with Easter Eggs, so here is one for GameFAQs. Even if you find something funny, post it. Heres some:
The Homeless drunk who sits ontop of the Downtown bank Statue at night.
The Wrestler Candy man, talk to him, he usually has a yellow of blue suit on. and you'll laugh!) (he can alays be found at the Caravan Park
Octavio, the guy in a suit who gets shot in the Babylon Club in the film, you can sometimes find him walking around Miami, Ive found him once at a car park in North Beach.
"Babe island" An Island that has nothing but girls on it.
"Gilligans Island" An old TV show with people from a Shipwreck living on an Island, there is one with a few people on it that apparently resemble the cast from the show.
