THE PERFECT LONDON WALK. By Roger Ebert and Daniel Curley. Andrews McMeel. LONDON -- "When I'm in London," Roger Ebert once said, "I hardly ever go to the movies."Ebert died on April 4, at age 70. Much has been written about his elegant prose, his film industry clout, his hallowed public standing and, in the end, his fortitude in the face of cancer. But much less is known about another essential Ebertism: his anglophilia. Ebert -- the lifelong Chicago newspaperman -- loved Britain. Each year he visited at least once, but often many times. He dreamed of moving to London. In his 2011 memoir "Life Itself," he wrote, "I felt a freedom in London I've never felt anywhere."
