Nolan addressed the issue of the French ship bring used:I'm going to be this one but...
WTF Nolan... You didn't put ANY effort in historical accuracy ? I'm no history buff at all but... You didn't edit the GIANT SHIPPING CRANES in the back drop of the city ? We see them in a dozen shots. The huge ass plastic covered factory ? The opening shots, all the plastic covers and wires running on the houses ?
It's like... They just... Didn't care ? They removed the cars and said good enough. We are miles behind David Fincher's Zodiac in term of post process CGI to remove and replace to match accurately or trying, a time period.
Also, the Maillé Brézé, the huge ass grey ship we see standing IDLE in water several times (with men on deck waving)... It's a french post war destroyer (a musuem ship in France) it has no propulsion anymore and it was towed for the shooting but... They barely worked on it. It doesn't look anything like a RN ship and its so obvious it's sitting in water : none of the big ships had wake they just all stood there, sitting in water...
Same for the little boats... it felt so cheap, so few of them on screen...
Its very weird because on top of these comments I made, some shots are just out of this world, breathtaking or superb.

Another example is the British destroyer seen in the film. Functional destroyers are hard to come by, and the one used on location is French.
"For someone extremely knowledgeable, they will see the differences. Its a bigger boat, and longer," says Nolan. "But we dressed it to make it look like a British destroyer.
"But the funny thing is, the veracity of being onboard a real boat in real water trumped the historical accuracy of making a perfect (computer graphic) model," Nolan adds. "We could have made a historically accurate model. But it wouldnt be real."
