A friend and I were discussing fantasy double bills, here is my Italian choice ... two of our timeless favourites, discussed many times here, as per labels. Rossellini's 1953 classic VOYAGE TO ITALY (below) with Antonioni's L'AVVENTURA. The Rossellini really paved the way for those Antonioni classics.
Below: Jean-Claude Brialy and Tomas Milian in a rather steamy scene (for 1959) from LA NOTTE BRAVA.
For Italian glamour and decadence, one could not beat Bertolucci's THE CONFORMIST with a Visconti: THE LEOPARD or his final masterpiece L'INNOCENTE from 1976.
