Promises are promises. The only fair argument the heirs could do is to claim the father didn't understand his decision to not wanting to publish the script.
Yes, but if there’s only one party that can be wronged by breaking the promise (e.g. feeling bad you broke a promise to your dead father), it becomes a bit different.
Sure, most people would feel terrible about doing that. But you would keep that promise out of respect, not because the dead are hurt by breaking it.
