Help please, stuck on last four. 1.When did the first proper passenger railway open in England? I thought Stockton & Darlington, but not sure and I can't seem to find a definitive answer on the web. 2. In which 1992 film did the Royal Naval College, Greenwich stand in for Buckingham Palace? 3. What is the name of the scabby eruptions that sometimes occur behind a horse's knee? I can only think of chestnuts, but they're on the inside of the knee and they're permanent. 4. Where is the fortune hidden in the 1963 film "Charade"? I'd be grateful for any help - and for anyone looking for the answer to Q.8, the play is Richard II, not III!
