I don't have an issue with copying the cast and crew from a previously approved profile for pending releases.  For existing releases, I'll usually copy an existing profile, if one doesn't already exist, and then review the film credits and make the necessary changes.

However, I agree that the cast and crew shouldn't be taken from an older profile and simply pasted over a newer one.  I can understand, to an extent, if someone did a complete review and are updating multiple profiles, but there are cases where the credits aren't the same even if it's the same film title.  So, it would be my preference to not copy over data wholesale unless people have those titles and have confirmed the changes.

I voted no too. Looks like a lot of the information is incorrect.

I would only copy/paste Cast and Crew if it was superior information, but even then I try to check it myself.

I think a good practice when contributing changes of any sort is to read the submission record before hitting Submit, as sometimes that way you learn why a particular profile has such and such info. If someone initially thought that another UPC had more thorough cast/crew, started the contribution process, and then read the notes that said the the cast/crew had been audited, the right thing to do would have been to either withdraw the submission or let the contribution lapse without hitting Submit. Doing either of those, no harm no foul. But if you try to change something that had been audited without addressing the audit, that's plain carelessness.
