Factual error: In the Shinkansen fighting scene, the railway line is seen having color light signals along its way. But the Shinkansen uses a signalling system that doesn't involve the use of light signals at all.
Factual error: The bombing altitude for Nagasaki was 30 000 feet (~10 km), but in the opening scene the planes bombing Nagasaki are a lot lower than that. The bomb also detonated at 1,500 feet, not at ground level as shown. (00:03:25)
Factual error: In the scene where Wolverine fights the ninjas on the bullet trains: 1) the shinkansen bullet trains are electric and have pantographs and overhead power lines - neither are visible. 2) None of the bullet trains have skylights.
Chosen answer: It was the first issue of the Wolverine comic, the 1982 limited series by Chris Claremont and Frank Miller.
