Even if Tony wanted a 2D train there were instances when we couldn't manipulate the photography as such in some cases the train had to go off the rails and we couldn't always do that in 2D so we had to be prepared with a 3D back-up plan." "We modeled, textured, lit and animated a photoreal CG 777. "The long and short of it is that we knew we were going to have to build a CG train," McGuinness admits. It is a simple premise, but as a film it begs to be a gritty and unquestionably real experience. Indeed, aside from the actors, the main character of the film is a train: two large engines and 25 train cars, out-of-control and speeding toward an inevitable disaster. It makes the audience feel that they are really watching a runaway train." With photography and Tony's great visual skill, we were able to make the trains run at a much faster rate than what we were capturing in real life. From the moment the 777 becomes an un-manned vehicle, it becomes its own creature. "The challenge was dealing with these trains, which were the third character in this film, and give the impression that this was a non-stop thrill ride from start to finish. And then when I have to I'm under immense pressure to make sure that it matches the photography so it doesn't look like visual effects.

So what I have to do is be a supporter of Tony's rather than a problem solver trying to fix it in post using visual effects. "I'm always trying to figure out solutions to not doing visual effects, which is bizarre. "Tony definitely tries to do everything he can in camera and he will take that to the extreme, which poses challenges for us," McGuinness suggests. "This is not a visual effects movie," emphasizes Nathan McGuinness of Asylum VFX, a long-time collaborator with director Tony Scott, who nonetheless supervised the vfx with Asylum colleague Paul O'Shea. Inspired by a true story, a runaway train carrying a cargo of toxic chemicals pits an engineer (Denzel Washington) and a conductor (Chris Pine) in a race against time before it derails and destroys a Pennsylvania town.
