Hindsight is 20/20.
But at least no one needs to know where you screwed up.
But when you direct a show, and watch your editor go through the stuff you’ve done, you really want to knock yourself on the head and ask “Why didn’t I see that? Why didn’t I get that right?”
Suddenly it seems all so clear, everything you should have seen on the day of the shoot. Should have spotted on the shoot. Should have fixed on the shoot. Should have told the actor this and that.
Now you’re stuck with the commitments you made, imprinted on tape and you can’t erase it. It’s got to go on air.
And you pray and hope hard, no one else has 20/20 when they watch what you’ve done.
