Respectfully, I'e seen the movie at least a dozen times, and you are the very first person I've ever spoken to who seems to think they jumped off the cliff. It did not happen. If you think it did, I would question if you actually saw the same film.
Additionally, the links you added do not support the additional informatio you wish to add. A lot of the info being added is your observations, and while you might be a spiffy gentleman (or gentle-woman), your observations are not citable. 
Lastly, realize that not everything that is citable is not necessarily notable. -  (cast a spell) "
