Original ending

While doing some searching, I discovered what appears to be the original ending to Jetsons: The Movie. It was later cut out of the film and replaced with the ending that's in there now. Apparently it was cut due to its dark nature and it was out of respect for Mel Blanc.
It begins right when the Jetsons escape the drilling bore and confront Spacely on the surface. The same dialogue is exchanged, trying to convince Spacely that what he's done is wrong. That his drilling is destroying the Grungees' homes. It's even discovered that Spacely knew about them all along, as pointed out by George. But Spacely won't listen to reason and is bent on achieving his billionth sprocket, no matter what it takes. Just as he prepares to start the machines again, the little Grungees, once small, loveable, cuddly Ewok creatures become almost demonic. Glowing red eyes, anger...they proceed to pick up Mr. Spacely and carry him off, pleading for George to save him. But George and the rest of them are too awestruck and nervous to do anything as they witness the Grungees throw Spacely over the edge of the balcony, screaming "JETSON!!" as he descends, and falls into his machinery. Though we don't see what actually happens to him, the Jetsons cringe and look away. The Grungees aren't finished yet. They proceed to dismantle the plant as the Jetsons leave in awkward silence. The entire plant collapses into a heap, with the material recycled and used to rebuild the Grungee society.
As the family is packing up to return to Earth, Jane asks if they're going to attend Spacely's funeral. George doesn't think so since he has an interview at Cogswell Cogs that day. Besides his grieving widow, once discovering she is the sole executor to his estate, is no longer grieving and plans to shoot her husband's remains into space.

This was cut from the movie because while it was being shot, Mel Blanc passed away and they deemed it inappropriate to show his character having a violent death around the time his voice artist died, so the scene was cut, footage destroyed, and the alternate ending was put in instead.

By the way, this is NOT the original ending, the subject is just a JOKE. This is simply MY alternate ending entirely made up in my head.
