I was very excited to see the American Reunion movie. I saw American Pie just after college and remembered it was quite funny.
Jim, Michelle, Oz, Heather, Stifler reunite for their high school...
Heather Graham's role in Hangover is essentially "cute smiling prostitute who takes her boob out." I don't think it's incomprehensible that Phillips offered that role to Lohan. I also don't think it's incomprehensible that a mediocre actress with higher aspirations (aka Lohan) would turn that role down.
I can't imagine Lindsay pulling off the role ... unless they re-wrote the role as a really world-weary, beaten down stripper. Heather Graham pulled it off great. Especially with her sad and glassy eyes at the end.
