I really dont understand your point. Take after take is normal for film. You literally cant compare film with stage, it's like comparing art galleries of paintings with photographs. Singing take after take is completely gruelling , which is why I said you have to divorce the stage and film versions from each other.
I'd agree there's nothing like a live audience in a stage setting. Film is a totally different beast. Every flaw is magnified 100 times.
My point is that there is nothing special about having take after take till you get it right.
