38. It's a film from years ago although I must admit I didn't get the 'Roger bit'
50. It's a person on board a merchant ship, the name of a chair and Byron's dog
52. It's an anagram of Carol and gold and Dean doesn't refer to a particular person, think religious man.
53. I really liked this answer. I think it was Australian slang. Something a coffin is placed on with street going back in the middle of it.
Hope these hints are helpful
