I found it very difficult to explain to someone why you did a film. It's not like having a conversation.
With any good story, you need the adversary, the heroes and villains. You need a good mixture to make it work.
You can alter movie singing so much because you go into the recording studio and, just technology for recording has gotten so good, you can hold out a note and they can combine a note from take 2 and a note from take 8.
