Frank Miller is regarded as one of the most influential and awarded creators. He began his career in comics in the late 1970s, first gaining notoriety as the artist, and later writer, of Daredevil for Marvel Comics. Next, came the science-fiction samurai drama Ronin, followed by the groundbreaking Batman: The Dark Knight Returns and Batman: Year One with artist David Mazzuchelli. Following these seminal works, Miller fulfilled a lifelong dream by doing an all-out crime series, Sin City, which spawned two blockbuster films that he co-directed with Robert Rodriguez. Miller’s multi-award-winning graphic novel 300 was also adapted into a highly successful film by Zack Snyder. His upcoming memoir, Push the Wall: My Life, Writing, Drawing, and the Art of Storytelling, is now available for pre-order.This episode is brought to you by: Eight Sleep Pod Cover 5 sleeping solution for dynamic cooling and heating: EightSleep.com/Tim (use code TIM to get $350 off your very own Pod 5 Ultra.)Shopify
