Where but in an awesome international city like London can you go up to a world renowned arts venue such as the Barbican of an evening and watch a film like The Wall? This 2003 film explores Israel, and it’s foolish attempt to build a wall  to prevent  attacks from Palestinian terrorists. The screening was followed by an interview with the director. Even though some of the shots lingered a bit too long for my taste, it really was a powerful piece, made even more resonant now by the fact that other, arguably even more idiotic walls are being built elsewhere. It’s  the type of film which makes  you reflect on how lucky you are to live in an open, tolerant, diverse  city like London; indeed, a city where such powerful films are screened.
