One thing I found curious about the advice is it suggests opening with the protagonist doing something she loves or is great at. Sound advice. However, in the 30 second slush pile readings I've been to, if there isn't clear conflict by the fifth sentence, the story gets gonged. I wonder if perhaps movies actually have less narrative urgency than popular fiction today, at least in openings. Two minutes of the protagonist surfing, running up mountains, or threatening piles of stone with a wooden sword can be entertaining on film, owing to its visual appeal. From what I understand, prose fiction doesn't have that luxury. To be commercially viable, it needs conflict now.
