When something not turning out "as you expected" means that there is a high potential for death or injury to /an uninvolved party/, then absolutely you have failed in your responsibilities, especially when it is something that your planning or contingencies could and should have accounted for.
I guess, then, by your logic, if no-one was responsible, there will be no compensation, right? After all, not their fault that a cannonball just happened to rip through someone's house. What an outdated idea, indeed.
(Though of course, in reality, the production company / insurer will probably pay for all damage and some compensation while trying to make the homeowner sign a document stating that they accept no responsibility or liability and that it's a goodwill gesture).
