I just watched "The Dark Knight" again, after having seen it just once before at the cinema in 2008. One of the scenes that stuck with me was the ferry scene.
A ferry full of prisoners and a ferry full of other citizens are jammed by the Joker during the crossing. The Joker uses loudspeakers to tell the passengers on both boats that they have a detonator to blow up the other boat. If none of the boats is blown up by a certain time, he will detonate both boats.
On the prisoners' ferry, one of them throws the detonator overboard. Meanwhile the non-prisoners hold a vote in which they decide to blow up the other ferry, but no one has the courage to press the detonator. The only one who wants to take matters into his own hands silently puts down the detonator at the last moment. The Joker is overwhelmed by Batman. None of the ferries is shown exploding.
But I remember the scene very differently.
One of the non-prisoners activates the detonator, but the Joker lied to them all. The detonator does not blow up the other ferry, but the one it is on. The prisoners watch in astonishment as the ferry with the non-prisoners blows up.
I am completely surprised that the scene was missing, but I can find no evidence online that it existed as I remember it.
Are there different cuts of the movie? Or is this my most severe case of false memories?
