LOL: Lost Alternative Ending

What if I told you that the ending of the Lost finale was not the only ending filmed for the series?

...That Damon Lindelof and Carlton Cuse wrote a completely alternative ending to the series?

Okay, well, it isn't true.

The three "alternative endings" that Damon and Carlton premiered on the Jimmy Kimmel show is as close to we'll ever get from official sources.

But this new "alternative ending" to Lost has appeared on YouTube. Watch it now after the jump.
