St Elmo's Fire, The Brteakfast Club, Pretty in Pink, About Last Night, Some Kind Of Wonderful, Sixteen Candles, Ferris Buellers Day Off are all classics.
The Coreys were in some great 80's movies too such as The Lost Boys and License to Drive.
I know this is a movies thread but if anyone likes to read check out Looking for Andrew McCarthy by Jenny Colgan for a bit of brat pack nostalgia. Warning to the guys though, it is chick lit!!
