It's summer's other big London take-over. Between August and October, all 58 of Alfred Hitchcock's surviving films are screening at BFI Southbank – its biggest ever retrospective. Hitch never won a Best Director Oscar, but his films earned him the title 'The Master of Suspense'. The BFI season gives fans a chance to see his lesser-known early British masterpieces, including 1927's 'The Ring' (an inspiration for 'The Artist'). And, of course, Hitch's Hollywood classics will all be showing: 'Psycho', 'The Birds', 'Rear Window' and 'Vertigo' – which recently bumped 'Citizen Kane' off the top spot in 'Sight & Sound' magazine's poll of the 100 best films ever.
