Guests leaving the New Israel Fund dinner in London on Sunday night narrowly missed walking on to a film set. A little way down, actor Michael Fassbender had just finished shooting scenes for his next movie. But it wasn't exactly the most appropriate title, given that the dinner had been remembering Israeli Prime Minister Yitzhak Rabin on the 20th anniversary of his killing. Mr Fassbender is appearing in the film of the video game Assassin's Creed.
