Hitchcock's stuff are the best; you can never not cringe and wonder with 'The Birds', which is seriously one of the best I've seen from him ('Psycho' was ruined for me)
His 'Notorious' (Ingrid Bergman and Cary Grant) and 'Spellbound' (Ingrid Bergman and Gregory Peck) and 'North by Northwest' (Cary Grant and Eva Marie Saint) are some of my favourite as well.
Ingrid Bergman is so beautiful, and I love 'Casablanca' (with Bogie) and 'Gaslight' (with Joseph Cotton) and 'Anastasia'.
I love that depressing part of Russian history so much I'm going to name my future daughter Anastasia, pronounced their way. Or Ingrid, because I love her.
A Gary Grant classic outside of 'Arsenic and Old Lace' (which is AWESOME!) is 'His Girl Friday'. It is fast-paced, has a clever script and great chemistry between him and Rosalind Russell. And of course, 'The Philadelphia Story'!
And I'm not sure if this has been mentioned or if you have seen this since this is a literature classic but Greg Peck as Atticus in 'To Kill a Mockingbird' was just great. The whole movie put the entire situation back then in such perspective without losing the essence of the book.
I cannot go away from this thread without mentioning PAUL NEWMAN! He was one of my favourite actors of all time, and I still remember the day he died (my friend's birthday and she adores him too). And you have not lived until you have watched 'The Hustler' and 'Cool Hand Luke' because those were some great movies. And of course, 'Cat On A Hot Tin Roof' is a must-watch; Elizabeth Tyler is just so gorgeous.
I love James Dean's 'Rebel without a Cause'. It seems odd because I'm now the same age as him when he died and I can't imagine just not existing anymore.
And of course, Princess Grace Kelly! Her beautiful costumes in 'Rear Window' are just stunning, and I love 'Dial M for Murder' and 'To Catch a Thief'. It is also depressing when I first knew of her that she died 3 years to the day before I was born (Patrick Swayze of 'Dirty Dancing', which I love so dearly, also died on the same day last year)
Someone mentioned 'Some Like It Hot', and I love it too! Jack Lemmon and Marilyn Monroe... One of my other two favourite people in the world. But for Jack Lemmon, I love 'The Apartment' too (him and Shirley MacLaine). It is kind of the essential movie to watch, in my opinion.
'Breakfast at Tiffany' is good, but 'Roman Holiday' (with Greg Peck) is great! Audrey Hepburn is just so adorable and a delight to watch.
'Guess Who's Coming to Dinner?' is also great. And on television shows, I love 'I Love Lucy'; used to watch it on TV in the early mornings before I head off to school!
And obviously, the classic 'Wizard of Oz' and 'It's a Wonderful Life' and 'Singin in the Rain'. And Chaplin's 'The Great Dictator' was just so bittersweet.
Pretty much all I can think of for now. I have not actually started on Bogie/Bacall
I am unable to like 'Citizen Kane' and 'Gone with the Wind', but that is just me
