Poor Stupid Fuzzle Guy. Never try and bluff me, especially when it's so easy to check up on your claims through the internet. So I've spent the last 20 minutes visiting IMDB and Wikipedia for each of the films you just mentioned. Even once I corrected your spelling mistakes, I found that few of them were cancelled during principle photography - and even then mostly because the star had died! Most were, as I said previously, cancelled during pre-production.
Now, something you may find interesting is the Wikipedia article
Shelved, which lists a number of films that actually did get cancelled in or after principle photography. Even still this is FAR, FAR below the 80% statistic you quoted.
A Woman at the Sea - Do you mean A Woman
of the Sea? Because that was destroyed for tax purposes.
Arrive alive - was cancelled because it wasn't particularly funny.
Batman Triumphant - was cancelled during the script stage because Batman & Robin did so badly.
Batman vs Superman - never got past the script stage because director Wolfgang Peterson left to do Troy.
Creation - never got past the casting stage
Dark Blood - was cancelled because River Phoenix died
Game of Death - was half finished when Bruce Lee had to stop and do Enter the Dragon only to be screwed when he died.
It's All True - Studio pulled the plug on this one. It's a documentary so it's questionable how well you can compare it.
The Man who killed Don Quixote - I mentioned previously as the Terry Gilliam film (every website gives a different title) which experienced extraordinary problems.
My Best Friends Birthday - A film Tarantino did when he was young with absolutely no budget. Had problems with the footage produced by their crappy old camera so they gave up.
Revenge of the Old Queen - never got past the script stage.
Somethings Got To Give - Marylin Monroe was fired, rehired then died.
Superman Lives - never got past the script stage.
The Works - CG animated film that was never completed in the 70's. Read the
Wikipedia article for more detail.
