Ray Bradbury, the writer whose expansive flights of fantasy and vividly rendered space-scapes have provided the world with one of the most enduring speculative blueprints for the future, died Tuesday at age 91. Though he had his share of novels adapted for the big screen (most notably "Farenheit 451" in 1966 and "Something Wicked This Way Comes" in 1983), Bradbury's great strength was the short story, and the format best suited to showcase those works was the anthology TV series.
