Inspiration for Lost?
A plane full of beautiful people and a prisoner under armed guard crashes on a remote island inhabited by a big dinosaur that eats people.
The survivors split up into two groups.
A select handful go for help on a raft, but they are doomed.
One guy has no problem adjusting to island life and even tries to help the others. Some accept the help, others are mistrustful.
The only other person on the island is crazy.
Does this remind anyone of a hit TV show that started last season ... seven months after this movie debuted?
