Robert Towne wrote Chinatown, a script widely believed to be a masterpiece. He also wrote Mission : Impossible 2. Is there any evidence that his original script was reworked (maybe to Tom Cruise's ego?) to make the movie so blah? Maybe some people like it, but mostly, it seemed like a flop.
Did the studio or producers alter a good script, or is this close to what was intended? Was it already sub-par?
This is not about script doctors or alterations in general, but about this project specifically. Did the studio or producers change the script during production?
I am NOT asking for opinions. I want to know if the script was changed against Towne's will (or with his blessing)? Is the movie as we know it what he wrote? I am not after opinions. Just verifiable facts with sources.
