Take a trip back in time with us this week when we visit 1975 and fill in some gaps in our cinema knowledge by catching up with that year's nominees for Best Picture at the 47th annual Academy Awards. The Godfather Part II went home with the gold and has been baptised into the pantheon of film classics. But in this age of mass surveillance, why aren't more people talking about The Conversation? Is it inflammatory to say The Towering Inferno is a good movie? Does Lenny stand-up? Forget it, Jake, it's Chinatown.
