As revealed this morning on ABC’s “Good Morning America,” the production of “Lost” filmed three different endings to last night’s Season Four finale as a means of confounding any spoilers and sneak peeks.
Basically, it was the same final scene, but with three different people shown in the coffin …
There was the real scene, which we saw last night, showing Jeremy Bentham in the coffin to be … John Locke!

But they also apparently filmed one shot of the coffin with Sawyer in it, and one shot with Desmond in it.
Silly ruses, sure, but fun to think of the implications of each of those, especially Desmond …
