Hello :)
OMG according to me, I think the absolute best thing about Sabrina is the clothes she wears! I'm in love with them all!

Other films I suggest are Wait Until Dark (she's much older in this role and I think she does a fantastic job)
The Nuns Story
Personaly I found War and Peace a little ...mmm... dull and I didn't watch the end of it, but maybe you'll like it
Then there's My Fair Lady, oh and don't forget Funny Face-I love that one! Fred astaire is just tooo cute! (even though he was over 50!)

Hope that helps :)
