And if youre referring to that sequence of events to Lohans life, what does it matter? She's an actor. Sissy Spacek... wasnt an out of place girl that didnt fit anywhere. She was ya know....an actor? The same as Lohan. She just didnt happen to be so well known before Carrie.
The directors and casting people cant help it if you go into a movie with preconceived notions simply because of the persons personal experiences thats on you, not them.
I dont care who or why a person is cast, if they do a good job and the film is good, then ill enjoy it.
