My eyes and ears are still adjusting back to normality. Yesterday’s screening of Abel Gance’s Napoléon at the Royal Festival bombarded the senses and befuddled the brain. It was not, as you may have been warned, a marathon. The five-hours-forty-minutes running time appears to go by in a flash, powered along by Carl Davis’s invigorating orchestral score. I would happily watch it all again tomorrow and the next day, and for as many times as it took to get to the bottom of its many mysteries.
