frequent collaborator Russell Crowe commented, "I like being on Ridley's set because actors can perform [...] and the focus is on the performers." Paul M. Sammon, in his book Future Noir: The Making of Blade Runner, commented in an interview with Brmovie.com that Scott's relationship with his actors has improved considerably over the years. More recently during the filming of Scott's 2012 film, Prometheus, Charlize Theron praised the director's willingness to listen to suggestions from the cast for improvements in the way their characters are portrayed on screen. Theron worked alongside the writers and Scott to give more depth to her character during filming. When working on epics, Scott states, "there’s always the danger that the characters can get swamped" on a large canvas, before adding, "My model is David Lean, whose characters never got lost in the proscenium." Scott's work is identified for its striking visuals, with heroines also a common theme. His visual style, incorporating a detailed approach to production design and innovative, atmospheric lighting, has been influential on a subsequent generation of filmmakers. James Cameron commented, "I love Ridley's films and I love his filmmaking, I love the beauty of the photography, I love the visceral sense that you're there, that you're present." Scott commonly uses slow pacing until the action sequences. Examples include Alien and Blade Runner; the Los Angeles Times critic Sheila Benson, for example, would call the latter "Blade Crawler" "because it's so damn slow". Scott claims to have an eidetic memory, which he says aids him in visualising and storyboarding the scenes in his films. Scott has developed a method for filming intricate shots as swiftly as possible: "I like working, always, with a minimum of three cameras. [...] So those 50 set-ups [a day] might only be 25 set-ups except I'm covering in the set-up. So you're finished. I mean, if you take a little bit more time to prep on three cameras, or if it's a big stunt, eleven cameras, and – whilst it may take 45 minutes to set up – then when you're ready you say 'Action!', and you do three takes, two takes and is everybody happy? You say, 'Yeah, that's it.' So you move on." Artificial intelligence is a theme that appears in several of Scott's films including Blade Runner, Alien, and Prometheus.
