What Is the Difference Between a Pitch Deck and a Look Book?

Laurie Metcalfe: I'm so curious about this conversation about pitch decks for features. She says the word deck has become a very morphe, multi-defined thing. "I just am not positive that if you're leaning on that when you go in to sell something it's doing anyone any favors," she adds. But as a young writer,Metcalfe would work more on what is this amazing idea and how can I figure out the most fascinating, cool, innovative way to tell it?
