Corrected entry: When the Aragons were in danger of losing their crop to cold weather, they lit fires between the rows of grapevines and fan the warmed air between the plants. In several shots the flames and smoke get very close to the vines, with no harm to the plants. However, when Alberto accidentally starts the fire that ruins their farm, watch how the grapevines go up in flames - it's almost laughable how quickly they ignite. In one of the long shots of the vineyard during the fire it appears that some of the vines spontaneously combust.
Corrected entry: In his flashbacks of the war Keanu Reeves enters an orphanage. This is written above the door of the ruin. But since it is the second world war the place is located in either France or Germany and so the sign should be written in French or German.
Correction: While the fire in the vineyard did spread unrealistically quickly at times, this is not an error. When fires were lit to save the crop from frost, it was early spring with all the plants green and fruitful. It would be very difficult to set fire to these green vines. When the inferno occurred, it was the end of the season when they vineyard was barren and dried out. It is very possible for a fire to spread easily in plants in this condition.
