"Lost" was one of the most ambitious and talked-about television series of all time, and its series finale is still debated even after seven years.

Now, it turns out, that finale could've turned out very differently, if creators Damon Lindelof and Carlton Cuse had gotten their way. According to Entertainment Weekly, they originally intended to end the series with a big battle on top of a volcano between Jack (Matthew Fox) and Locke/Man in the Black (Terry O'Quinn).

Eagle-eyed fans spotted drawings and a model of a volcano in a Dharma Initiative classroom, but it seemed it was just another random detail. But it was actually there to hint at the endgame.

"The question was always, how do you basically visualize and dramatize the idea that the island itself is all that separates the world from hellfire and damnation? And the answer was the volcano," Lindelof explained.

The volcano was meant to be introduced in the episode that detailed the relationship between Jacob and the Man in Black; Jacob would kill his brother on the slopes of the volcano.

And then, in the final season, the island grew unstable. As Lindelof said, "We were going to have lots of seismic activity, and ultimately, there was going to be this big fight between the forces of good and the forces of evil, which ended up in the series manifesting as Jack and The Man in Black, in the midst of magma. Magma spewing everywhere!"

Unfortunately, the showrunners ran into a major obstacle: Money. Shooting the volcanic scene would've been too expensive, and ABC nixed the idea.

"The other thing that happened," Lindelof added, "was that we remembered 'Revenge of the Sith,' and that big epic battle between Anakin Skywalker and Obi-Wan Kenobi, in the midst of a volcanic planet. We knew whatever we did was going to look Mickey Mouse next to it."
