I was unable to find it on YouTube anywhere so, in case you haven't, here it is. I'd like to say no horses were harmed in the making of this scene, but I'm pretty sure at least one terrified horse was pushed into the sea by Irvin Kershner from a ruddy great platform in the name of entertainment.
EDIT
The shot that's often cut is the slow motion shot of the horse falling into the water.
I'm hope the horse was fine and there's no guarantee the animal swimming away was the same one as the one that falls. But it can't have been that dangerous or else the human stunt performers wouldn't have done it either! Also, it's not from the top of a castle (the first shot of the fall is clearly a matted on model), the fall itself may only be about 30 feet o so, but the slow motion makes it look further.
The reason it's always cut in the UK is due to complaints from the RSPCA and BBFC; there's no way of proving the horse wasn't forced to do this stunt against it's will.
