How do you confirm a real-life casting?
Confirmed Casting
<blockquote>How do you confirm a real-life casting?</blockquote>
To confirm a real-life casting, you'll click on the suggestion to navigate to the page that displays the suggested actor and their role. In the middle of the page, there is text that reads "Has this person been officially picked for this role? Click here." Click the link, add the URL for your source, and you're done!
And how to unconfirm a casting? Say, if someone's making a completely imaginary Batman movie, Ben Affleck or Christian Bale shouldn't be marked as confirmed, cause they can't have been confirmed for a movie that will never be made.
