So is Luke too famous? Is that why he has to disappear to nature? Or is he just like a regular guy who has had enough of the monotony, enough of the organized hoarding that is everyday life? Maybe show a few shots of him doing dishes, folding laundry, paying his taxes, shit that just makes a regular guy want to run screaming into the woods.
I like the idea of him trading down in a reverse paperclip kinda way. giving his flat screen tv to a bum for half a sandwich (turkey sandwich, with south african spices maybe? ps what are south african spices?)
I also like the idea of him coming out of the woods into san fran, but he should be changed in some way when he does. Maybe he's wearing like a cave man outfit? Space suit? Something to really set him apart from the people on the street, like he's come out of the woods a changed man. Even though he hasn't found what he's looking for yet, he's got a different VIEW of them now that he's gone through his woods transformation.
