Days of Heaven (1978)

Continuity mistake: Near the end of the film, when Richard Gere and Brooke Adams is by a boat and attempt to escape up the river, Gere is shown waving a kerosene "barn lantern" to illuminate the boat. In a slightly later shot, he is doing the same thing, but the lantern has become a Coleman gasoline lantern. These lanterns had not been invented yet in 1917, the year during which the scene in question takes place.

The Farmer: I always thought that being alone was just something that a man had to put up with. It was like I just got used to it.
