It's difficult not to place any Hitchcock film in a top ten

because in reality, they were all great films - But I'm asking for a personal group a group that keeps you enthralled always.

I have favorites like Suspicion and Birds. As for other films I lean to, Sexy Beast, the Kubrick Canon, Orson Wells canon, and so many others - you mention The Bicycle Thief and Cinema Paradiso with that I'd add The Icicle Thief and Il Postino, the Jules Dassin canon too. Metropolis, Far From Heaven, King Kong (original), Gone With the Wind, To Kill a Mocking Bird, Casablanca, The African Queen, Double Indemnity and so many others.
