Veteran director Woody Allen is unhappy with the current heatwave in London, because the hot weather is hindering his attempts to get the right look for his latest movie. Allen is in the British capital filming his next as-yet-untitled film starring Ewan McGregor and Colin Farrell. MCGregor says, "Woody is enjoying being here. But there's one problem - he really likes the light flat, so we're currently nobbling him with all this sunshine! "As a result, we've had to adjust the filming schedule."
